Siwa Oasis: the oracle, the salt lakes and the sand sea

Siwa is an oasis of about 25,000 people in Egypt’s Western Desert, fifty kilometres from the Libyan border and nineteen metres below sea level, with its own Berber language and a temple where Alexander the Great was told he was the son of a god. It is the least Egyptian place in Egypt, and it is not on the way to anywhere.

Short answer

Siwa Oasis lies between the Qattara Depression and the Great Sand Sea in the Western Desert, about 560 kilometres from Cairo and 50 kilometres east of the border with Libya, at 19 metres below sea level. Its people are Siwi and speak a Berber language. The oasis is known for the temple and oracle of Amun at Aghurmi, consulted by Alexander the Great, for the mud-brick ruins of the old town of Shali, for salt lakes and springs, and for the dunes of the Great Sand Sea. It is reached by road, most easily from Marsa Matrouh.

Siwa sits in a depression in Egypt’s Western Desert, between the Qattara Depression and the Great Sand Sea, about 560 kilometres from Cairo and fifty from the border with Libya. It is nineteen metres below sea level, it gets about twelve millimetres of rain a year, and the people who live there are Siwi: they speak their own Berber language and have done for a very long time. The ancient Egyptians called it the Oasis of Amun-Ra after the god whose oracle stood here, and for centuries it was a place people travelled a long way to reach.

They still do. Siwa is not on the way to anywhere, which is exactly why the oasis has kept its own shape: mud and salt architecture, a lake of brine, springs in the palm groves, and a town on a hill that was abandoned within living memory. The nearest city of any size is Marsa Matrouh on the Mediterranean coast, roughly 300 kilometres north.

The oracle, and the man who asked

The temple of Amun at Aghurmi was one of the ancient world’s famous oracles, and its reputation rests on a single visit: in 331 BC Alexander the Great made the journey from the Nile to ask the god whether he was the son of Zeus-Ammon. He was told what he came to hear, and never told anyone what else he had asked. The temple still stands on its outcrop above the palm groves, roofless and stripped, with the remains of the temple of Umm Ubayd a short walk away.

The rest of the antiquities are mostly funerary and mostly on the Mountain of the Dead, a ridge of rock-cut tombs with painted ceilings, and a few surviving inscriptions in Greek and Siwi. Between them lie the springs: some fresh enough to swim in, others so salt-heavy you float without trying, which is the source of every photograph of Siwa that has ever been taken.

Shali, the town that melted

Shali is the old town, built on a mound in the middle of the oasis out of kershef, a mixture of mud, salt and stone. It had grown into a small fortified hill of houses stacked on each other when, in 1926, three days of rain fell on a place built to expect none: the salt in the walls dissolved, the structure slumped, and the town was abandoned for the lower ground. What is left is a melting brown hill with paths through it, which is one of the strangest walks in Egypt.

The road in, and what to bring

Getting to Siwa is the largest part of going there. The standard route is the desert road from Marsa Matrouh, which is a long, straight drive with few services; buses also run from Cairo and Alexandria, which makes for a very long day. There is an airstrip at the oasis, but scheduled flights are not a thing to plan around, so treat this as a road trip and break it up.

Pack for two climates in one day. Winter days in Siwa are mild and the nights are cold enough for a real jacket, and summer is one of the hottest places in Egypt with almost no shade. Cash matters more here than anywhere else on the usual circuit: take what you need, because a card machine in the oasis is a hopeful object rather than a reliable one.

Average daily high at Siwa, by month

Twelve millimetres of rain in a year and two days on which it falls, which is the reason the old town of Shali is a ruin and the reason everything here is built of mud and salt.

Desert, water and the way of the place

West of the oasis begins the Great Sand Sea, an enormous field of dunes that runs to the Libyan border and beyond. The trip everyone ends up taking is a four by four into it, for a few hours or for a night under the stars, and it is worth arranging through a hotel that works with the same drivers year after year. Sandboarding, tea on a dune and the silence are the whole itinerary.

The oasis itself runs on a strict water arithmetic. The springs are fed from the desert aquifer, the palm groves are irrigated in turn by channels rather than all at once, and the great salt lake is the result of what is left over: drainage water that has evaporated down to brine. Swimming in it is a novelty; the fresh springs in the groves are the better afternoon, and they are usually free.

Siwa is conservative, and it is far from the institutions of the Nile valley. Dress modestly, ask before photographing people, and keep the desert trips with people your hotel can vouch for. None of that is unusual for rural Egypt; it simply applies with more force here, eight hours from the nearest hospital of any size.

What will you do with the desert day?

Do you want to sleep out in the sand sea?

Are you willing to get up before sunrise?

A night in the Great Sand Sea

A four by four takes you west into the dunes for the afternoon and back the next morning, with dinner and a mattress under the stars in between. Take more layers than you think you need, a head torch and water. This is the experience people remember from Siwa, and the reason to arrange it through a hotel that knows its drivers.

Sunrise over the dunes

The short version: out before first light, up the sand in the dark, and the light arriving across an unbroken horizon. You are back for breakfast. It costs a morning rather than a night and gives you most of the photographs, and the sand is cool enough to walk on while you wait.

The springs, the lakes and the temples

The oasis itself is a full day: the oracle temple at Aghurmi, the tomb hill, the ruined town on its mound, then a long afternoon of springs and salt lakes, with a swim in the ones that are fresh and a float in the ones that are not. Do the antiquities in the morning and the water in the heat.

For the oasis

Siwa rewards the journey precisely because the journey is inconvenient: an oracle that answered Alexander, a town that dissolved in the rain, salt you can float on and dunes that go on for a hundred kilometres. Give it three nights, take cash, and go between October and April.

Questions travellers ask

How do you get to Siwa?

By road, and it is a long way. The usual approach is from Marsa Matrouh on the Mediterranean coast, roughly 300 kilometres south by a desert road, which is why most people break the journey there. Buses also run from Cairo and Alexandria. There is an airstrip in the oasis, but scheduled passenger flights are not something to build a plan around, so treat Siwa as a road destination.

What is there to see?

The temple and oracle of Amun at Aghurmi, where Alexander the Great was greeted as the son of Zeus-Ammon in 331 BC, and the nearby temple of Umm Ubayd. The hill of Shali, the mud-brick town abandoned after rain soaked it in 1926. The Mountain of the Dead, with rock-cut tombs. The springs and the salt lakes, which are the colour of the photographs. And the Great Sand Sea to the west, for dunes.

Is Siwa safe for solo and female travellers?

Siwa is a conservative, close-knit community with its own customs, and women travellers report that it feels calm and that the attention is different from the big cities, though dress and behaviour expectations are more traditional. It is far from the Nile and from the police presence of a tourist town, so it is a place to use normal caution about where you walk after dark, to arrange desert trips through your hotel, and to read the current travel advice before setting out.

When should you go?

Late autumn to early spring. Siwa is one of the hottest places in Egypt in summer, and the chart below says why: from June to August the average daily high is around forty degrees in the shade, and there is not much shade. Winter days are pleasant and the nights are genuinely cold, so pack layers if you go between December and February.

How long does Siwa need?

Three nights is the honest minimum, because a day of the stay disappears into the road in each direction. That gives you a full day for the antiquities and the springs, and a second for the desert, which in practice means a morning or an evening of dunes, or a night camp in the sand sea. Two nights feels rushed; a week is a holiday.
