For seven hundred years the world’s maps treated this island as the jewel in the ring of the earth — the customs house of the planet’s richest strait, fought over by Persians, Portuguese and the English in turn. They all misread it. A treasure hides; Hormuz performs. The ground itself puts on the show — hills painted in seventy colours, a mountain of pure salt, a red soil so fine the islanders eat it.
Eight kilometres off the coast of Bandar Abbas, in the narrow throat of the Strait of Hormuz, an island sits in the Persian Gulf that looks, on satellite photos, like a single drop of red ink hitting blue water. This is Hormuz Island (جزیره هرمز), a 42-square-kilometre piece of geology so unusual that NASA has photographed it from orbit, that geologists call it a "salt diapir" (a teardrop-shaped mound of rock salt and evaporites that has slowly risen up through layers of overlying rock), and that locals call simply jazireh-ye rangi — the colourful island.
The island's core was laid down some 600 million years ago, in the Precambrian, and has been rising ever since. Surveys have catalogued more than seventy distinct shades of soil and rock across its hills; locals will tell you the real number is higher, and that nobody has bothered to count past a certain point.
But Hormuz is not only a geological curiosity. It may be the one place on Earth where geology, cuisine, fashion and folklore have all grown out of the same earth — literally. The red soil, known locally as gelak (گلک), is mined, eaten, painted with, and traded; the island's food, its art, and its women's bright dress all draw, in the end, on the ground itself.
And then there is the history. For seven hundred years this small island sat astride one of the world's great trade routes, rich enough that Europe used its name as a byword for wealth. Marco Polo, Ibn Battuta, and the Portuguese all came; the red fortress the Portuguese left on the northern tip still stands, weathered by the same iron oxide that paints everything else. The full story is below.
Almost everything you see on the island is a consequence of one fact: it is a salt dome — a buried layer of rock salt, lighter than the rock above it, that has slowly squeezed to the surface like toothpaste up a tube, carrying iron, clay and volcanic rock up with it. Exposed to rain, oxygen and sea spray, those minerals oxidise into the colours.
It is one of the most accessible mature salt diapirs on Earth — one of a family of domes studding this coast, another of which hollows into the great salt cave of Namakdan on neighbouring Qeshm. Its concentric rings are visible from space; its highest point is barely 186 metres. Geologists come for the textbook outcrops. Everyone else comes for the colours.
Few small islands have appeared in so many world chronicles. Hormuz has been Greek, Arab, Persian, Portuguese, and Iranian again — each layer leaves traces on the rocks and in the language. For two centuries Europe used the island’s very name as a synonym for wealth: when Milton needed an image for Satan’s throne in Paradise Lost, he wrote that it “far outshone the wealth of Ormus.”
Why is one hill red, the next gold, the next bottle-green? The answer is mineralogy: as the salt dome rose, it carried up rock layers of different chemistries, and each oxidises into its own colour in the air, water and sun. Four minerals do most of the painting.
The dominant colour of the island: gelak, rich in iron oxide — the same compound that makes blood red and Mars red. Hormuz's red ochre has by some accounts been ranked second only to Spain's. Add the green of altered basalt, the black of magnetite, and the silver glitter of pyrite sand, and the palette runs past seventy shades.
Where hematite has interacted with water, it has weathered to goethite — softer yellows and rust-golds. The Rainbow Valley's gold bands come mostly from this.
The salt itself. Pure rock salt (halite) is colourless to white. Mixed with the volcanic rhyolite and gypsum that the salt dome carried up, it forms the pale outcrops at the Salt Goddess and along the southern shore.
Less common, but striking where it appears: streaks of bottle-green and teal in the Rainbow Valley walls. The result of weathered iron-magnesium silicates in altered basalt.
Of all the strange things on Hormuz, the strangest is also the most ordinary, in that the people of the island have been doing it for centuries: they eat the ground beneath their feet.
The red ochre soil — called gelak (گلک), or sometimes dolak — is, as far as anyone has found, the only soil on Earth that forms part of a living cuisine. Islanders process it at home into a deep red sauce called soraq (سوراغ) that flavours fish, breads, pickles, jams, and a beloved stew of the same name.
The technique has not changed in living memory. Women gather small quantities of the cleanest red soil from the foot of the red mountain (only a few percent of the available soil is now permitted to be taken; the rest is environmentally protected). The soil is sifted and mixed with water in a clay vessel. After several hours the sediment settles, and a thick, vivid red liquid is decanted off the top.
To this liquid is added salt, bitter orange peel (پوست نارنج), lime juice, and small whole sardines — known locally as mumagh, moto, or heshineh. The mixture is sealed in a clay jar and left in the sun. After roughly one to two months of slow solar fermentation, the result is soraq: a deep, savoury, umami-rich earth-sauce unlike anything else in Persian cuisine.
The first taste is unexpected. It is not what you expect dirt to taste like. It is faintly salty, faintly metallic in the way good iron-rich water is, with a fishy, citrus, ferment-edged depth that makes sense once you stop thinking of it as soil and start thinking of it as a fermented condiment. Locals sometimes offer visitors a tiny taste of the cleaned soil directly on the beach — something best experienced in moderation and from trusted local sources.
Nadalian's point carries a warning as well as a recipe. He has long argued that the island's true wealth is being undersold: for years a local company exported the coloured earth in bulk to be used as an industrial pigment, while many islanders lived on little income. Reframing the soil as something to eat, paint, and sell as craft — rather than something to mine and ship away — has become a quiet form of conservation.
Around the soil-sauce runs the best of southern Gulf cooking, all dried lime and tamarind: ghalyeh mahi, the famous tangy fish stew, and mahyaveh, a pungent fermented-fish sauce that is the Gulf's answer to Vietnamese nuoc mam. But soraq is the one dish you will find nowhere else on Earth.
The women of Hormuz dress in a style called bandari (literally "of the ports"), shared along the whole Hormozgan coast and worn here in especially bright form. It is one of Iran's most distinctive regional dress traditions, and on Hormuz it is still everyday wear rather than costume. Four elements make up the look:
A knee-length, body-fitted dress with a deep, wide embroidered band around the waist. Cut from cotton for daily wear, or satin and zari for weddings and feasts. Worn over the bandari trousers, which it frames. Some accounts link the word, and the garment, to the loose gandura tunic found across the Arab world and the Mediterranean, though the connection is debated.
The signature trousers: tight around the calf and ankle, looser through the thigh, in bright greens, reds, yellows, oranges, and blues. The lower section is heavily embroidered — sequins, gold thread (gelabton), khus-work made from date-palm fibre, and the dense regional needlework called vodui. A wedding pair can take a craftswoman months to finish.
The famous face mask of the Persian Gulf — a stiffened piece of fabric covering the brow, nose, and upper cheeks, leaving the eyes and mouth free. Originally adopted as protection from the intense Gulf sun, salt spray, and dust, the borqa has become both garment and jewellery, with families passing down decorated examples through generations. Some are bronze-coloured, some indigo, some red; the shape and ornament shifts subtly from village to village.
A long silk or chiffon headscarf, embroidered with floral and boteh (paisley) motifs in metallic gold and silver thread. Wrapped around the head and shoulders with one end flung loose over the chest — a movement locals call kol. In bright reds, oranges, emerald greens, and saffron yellows that flash from a distance.
For decades the embroidery was kept alive inside Hormuzi homes, made by women for their own families. The Nadalian Museum (below) changed that — inviting the island's women to paint with the coloured soils and sell their work for their own income. The bazaar near the Portuguese Castle is now run almost entirely by Hormuzi women, selling embroidery, borqa, dried spices, soraq jars, and salt-glass jewellery. Buying from them is the single most useful thing a visitor to the island can do.
Most visitors come for the Red Beach. They should also see this:
The island's emblem. The southern shore, where iron-oxide soil meets the Gulf and turns the waves pink for several metres offshore. Walking the beach stains shoes and clothes deep red (washable). Best photographed at sunrise or sunset, when the light intensifies the colour.
A small valley a short drive south-west of Hormuz town where more than seventy colour bands are visible in the surrounding hills. Geometric patches of red, gold, white, black, and teal that look almost painted. Best in late afternoon during golden hour.
A salt mountain in the south of the island, eroded into smooth white walls and a low dome. An underground stream runs through caves at its base, coloured bright orange by iron. Locals say the salt absorbs negative energy. Either way, it is quiet and worth the short detour.
A cluster of wind-carved black volcanic formations that resemble figures and animals. A short walk from the road. Dusk is the best light, when the shadows lengthen the shapes.
The 500-year-old fortress built by Afonso de Albuquerque in 1507. Once 20,000 square metres; now about 15,000 remain. Walls 3.5 metres thick, four square towers, weathered red by the same iron oxide that paints the island. Officially named Forte de Nossa Senhora da Conceição. National heritage site since 1998.
A short walk west of the Red Beach, where the same coast suddenly turns silver — fine pyrite and mica flakes glittering in the sand. Best seen with the sun directly overhead.
The cultural heart of the island. A renovated old house in Hormuz town displaying works made entirely from coloured soils, embroidery by Hormuzi women, environmental art, and recycled-material dolls. Open daily 8am to 10pm. Income supports local women artists.
A 30–40 metre sea cave in the west of the island, carved through the base of the salt mountain by waves. Its walls alternate between bands of hematite (red) and halite (white-grey). Accessible only by boat at low tide.
Hormuz is small, low, and salty, so its wildlife is modest rather than spectacular. The interest lies in the contrast between the dry interior and the productive water around it.
Inland, the flat scrub plain — the Plain of the Gazelles (Dasht-e Ahuvan) — holds a small population of jebeer, the regional goitered gazelle. They graze in the open and are most often seen at dawn. Foxes, hares, lizards, and several snake species also live in the interior. In winter, the southern salt flats and tidal margins draw migratory shorebirds.
Offshore is the richer side. Green sea turtles nest on the eastern beaches at night between roughly April and June. Indo-Pacific dolphins are regularly seen from the Bandar Abbas boat. The shallow reefs along the southern shore support corals, parrotfish, butterflyfish, and sea urchins, along with a diverse community of zoanthids (small soft-coral relatives) that has drawn recent marine-survey attention. A list, not a safari — set expectations accordingly.
Untamed Iran rates each destination on two separate dimensions — Adventure, the physical demands a place makes on you, and Legacy, the weight it carries in geology, history, and culture. Hormuz scores low on the first and high on the second: it is an easy place to reach and walk, and a hard place to forget.
It is the second afternoon, on the Red Beach, around four. The first day was overload — too much red, too much sun — but now the heat has dropped and the colour has deepened, the sea the shade of cooled blood near the shore, fading to turquoise where the iron thins. A woman in a green kandoureh sits on the rocks, grinding red soil between two stones. The wind has fallen, and you can hear it: one stone on another, a sound the island has been making far longer than anyone has been here to hear it.
That is when it lands. Since the ferry, the island has been performing for you — painting its hills, cooling its afternoons, offering its own red body to eat. A bird that wants to be seen fans its feathers and dances; the ground of Hormuz does the same, and the display is for you. You sit down. You stop taking pictures. You stay until the sun goes.
Dance is what a living thing does when it wants to be seen: the brightest feathers, the whole repertoire, everything offered at once. On this island the dancer is the ground itself — seventy colours, a salt mountain, an earth you can eat. Empires fought seven hundred years to own the stage. The dance was always free.
I had seen Hormuz a thousand times before I ever went — Instagram, Google, image after image — and I counted down the days. For weeks beforehand I kept asking myself where I would smoke my cigarette there. On the beach itself? Somewhere up on the red hills? The Portuguese castle? The Valley of Statues? Facing the Goddess of Salt? The middle of Rainbow Valley? Out on the gazelle plain?
The argument in my head reached no verdict. So I decided to decide in the moment.
I went everywhere. And everywhere I was lost in a beauty I had never seen the like of, which only made the choice harder — harder with every stop. I didn't smoke it. I couldn't.
I had to be back in Qeshm before sunset, so I made my decision by not making it. We boarded a motorboat with a group of young students from Shiraz, boys and girls travelling together, and I was still in shock from all that display when one of the boys asked the driver to slow down. He turned up the portable speaker he'd brought, and they began to dance and sing along. Bandari music, their voices, their dancing, the setting sun behind it all. I took out my cigarette and lit it.
The first comfortable weeks after the killing summer heat passes. Sea still warm enough to swim, light beginning to soften, fewer visitors. Excellent.
The peak season. Days are warm (20–25°C), nights mild, sea calm. Most tour packages and Nowruz visitors arrive in late winter and early spring. Bookings get tight near Nowruz (late March).
Nowruz brings warm days and the island's busiest crowds, especially around the spring holidays and Persian Gulf Day. If a Soil Carpet event is scheduled, this is often when it lands. Beautiful but busy.
Avoid. Temperatures hit 40°C and humidity from the Gulf makes it brutal. Most guesthouses scale back operations. Salt crystals on the soil reflect the heat onto your face. Locals leave for cooler mountains.
⏰ The Soil Carpet of Hormuz (Farsh-e Khaki) — a giant ground painting made entirely from the island's coloured soils by dozens of local and visiting artists — has been staged most years since around 2008–2009, usually in the cooler autumn-to-spring window rather than on a single fixed date. Sources disagree on its exact scale (variously reported at roughly 1,300 to 1,600 square metres and using anywhere from 18 to 90 soil colours), and on whether it formally holds a world record, so treat the "world's largest" billing with mild caution. The dates shift year to year; confirm locally before planning a trip around it.
Hormuz is remote but not difficult — one mainland city, one short ferry, and a sun that must be taken seriously. The detail is folded away below.
The whole logistics chain hangs off one mainland city — Bandar Abbas — and one short ferry. Prices move with the rial, so treat figures as orders of magnitude rather than quotes.
Yes, in a specific sense. The red ochre soil, gelak, is used by islanders as a mineral seasoning and as the base of the fermented dish soraq. It is roughly 70% iron oxide. Locals eat it in small quantities and prepared in traditional ways; it is not a snack to be shovelled by the handful, and visitors should only taste cleaned soil offered by a trusted local source.
Fly to Bandar Abbas (BND), then take a passenger ferry from the Shahid Haqqani terminal. The crossing is about 30–60 minutes. There is also a ferry route via Qeshm Island. A day-trip is possible but rushed; staying one or two nights is much better.
Roughly October to March. Days are warm and pleasant, nights mild, the sea calm. From May to September the island is very hot and humid and many guesthouses scale back. Nowruz (late March) is beautiful but crowded.
No special permit is required — Hormuz is an ordinary domestic destination. A guide is not mandatory but is strongly recommended, both for getting around (the sights are scattered and there is no public transport) and for finding safe soil to taste and the best home-cooked food. Note that the surrounding Strait is a sensitive zone: do not photograph naval or port installations.
No. Foreign-issued cards do not work anywhere in Iran. Bring enough Iranian rials in cash from Bandar Abbas, with small notes for the bazaar, or arrange a pre-loaded local tourist debit card through a travel agency before you arrive.
No, and you are asked not to. Soil extraction is now largely restricted to protect the island's surface, and souvenir-taking has caused visible damage. Buy embroidery, borqa, soraq jars, or soil paintings made by local women instead — this supports the community and keeps the soil where it belongs.
Two to three days covers the main sights at a relaxed pace: the Red Beach, Rainbow Valley, the Salt Goddess, the Portuguese Castle, and the Nadalian Museum, with time for the food. Combined with neighbouring Qeshm, the region rewards a full week.
Hormuz pairs naturally with its giant neighbour Qeshm, a UNESCO Global Geopark one ferry away — where the same salt series that painted Hormuz hollows into the great salt cave of Namakdan, the earth splits open at Chahkooh Canyon, and erosion has carved the badlands of the Valley of Stars. On the mainland, Bandar Abbas has the ferry, the fish market, and the Friday crafts market. And for the longer story this island belongs to: centuries before Hormuz wore the title, the Gulf’s great port was Siraf, far up the coast — the trade that crowned one island had already made and unmade another. The whole region rewards at least a week.
Untamed Iran prefers official, scientific, and first-hand sources, and flags where the record disagrees with itself. The geology, dimensions, history, and cultural detail above draw on the following:
Facts last reviewed June 2026. Established: the de Barros “jewel” saying and Milton’s “wealth of Ormus” are documented period sources; the Portuguese held Hormuz 1507–1622; William Baffin was killed at the preliminary assault on Qeshm in January 1622, before the fortress fell after a ten-week siege. Hedged: Marco Polo’s visits (c. 1272 and the 1290s) were to the then-mainland port of Old Hormuz; the “only edible-soil cuisine” and “second-finest ochre” claims are widely repeated but not formally certified; the exact 1622 surrender date differs between old and new calendars. Practical: prices, ferry times, and festival dates change frequently — always confirm locally before you travel.
