Erg Chegaga from Ouarzazate: Route, 4x4 Piste and Desert Camps

Erg Chegaga is the largest field of sand dunes in Morocco and the wildest one you can reach from Ouarzazate. Getting there takes two stages: about 260 km of paved road south through the Draa valley, Zagora and M'Hamid El Ghizlane, then 50 to 60 km of desert piste that only a 4x4 with an experienced driver should attempt. Most travellers need three days for the round trip.

This guide explains the route step by step, how Erg Chegaga compares with Erg Chebbi at Merzouga, what the camps are like, why Lake Iriqui is usually dry, how the Foum Zguid loop works and when to go. It is written for people starting from Ouarzazate, which is where most Chegaga trips begin and end.

What Erg Chegaga is

An erg is a sea of sand dunes. Erg Chegaga (also spelled Chigaga or Chgaga) lies in the far south of the Draa valley, roughly 50 to 60 km west of M'Hamid El Ghizlane, a town that is itself only about 24 km from the Algerian border. Local operators describe it as about 40 km long from east to west, much larger than Erg Chebbi, which measures roughly 28 km from north to south.

Its tallest dunes rise about 50 to 60 metres above the surrounding gravel plain, sometimes a little more after strong winds reshape them. Between the dune ridges you find flat stretches of hamada (stony desert), tamarisk and acacia trees, and a few wells used by nomadic herders. The western edge of the erg borders the Iriqui National Park.

What makes Chegaga different is not the height of the sand but the space. There is no village at the foot of the dunes, no paved road and no electricity grid. The camps are scattered and far apart, and at night the only lights you see are your own camp and the stars.

Erg Chegaga or Erg Chebbi (Merzouga)?

This is the question we hear most often from guests planning a desert night. Both are real Saharan dunes; they suit different trips. Our Ouarzazate to Merzouga guide covers the eastern route in detail, so here is a short comparison.

Choose Merzouga if you want the tallest dunes, an easy paved road and the widest choice of camps. Choose Erg Chegaga if solitude matters more than dune height, if you do not mind a long bumpy ride, and if you like the idea of the Draa valley's palm groves and kasbahs on the way. Families with young children, or anyone who gets carsick, usually find Merzouga easier.

How to get to Erg Chegaga from Ouarzazate

The classic route follows the N9 south to its end at M'Hamid, then leaves the tarmac for the piste. All distances are approximate.

Ouarzazate to Zagora through the Draa valley

The first half of the drive is one of the finest roads in the south. After the Tizi n'Tinififft pass, the N9 drops to Agdz and then follows the Draa river through long palm groves lined with earthen ksour and kasbahs. Zagora is about 165 km and 3 hours from Ouarzazate. We cover this stretch, its stops and its kasbahs in our guide to the Draa valley and Zagora, so we will not repeat it here.

Zagora to M'Hamid El Ghizlane

South of Zagora the valley becomes drier and the villages smaller. About 20 km from Zagora, Tamegroute is worth a short stop for its zawiya library of old manuscripts and its workshops of green glazed pottery. A few kilometres further, the small Tinfou dunes appear beside the road: pretty, but only a foretaste. The road then crosses the Jbel Bani ridge and reaches M'Hamid El Ghizlane, about 97 km from Zagora, where the N9 ends.

M'Hamid is a small oasis town on the Draa, which rarely carries water this far south. It lives largely from desert tourism, and it is where you leave any rental car and meet your 4x4 driver or camp transfer. Expect people offering tours as you arrive; if you have already booked, simply say so and head to your meeting point.

The 4x4 piste from M'Hamid to the dunes

From M'Hamid, the piste heads west across hamada, dry riverbeds and patches of soft sand. There are several parallel tracks and no signposts. Drivers usually stop at the small oasis of Oum Laalag, a traditional caravan halt with a well, and some routes pass the low dunes of Erg Lihoudi closer to town. The ride is bumpy and dusty, and its length depends on the track chosen, the state of the sand and the stops: count on around 2 hours, sometimes more.

The piste is not a place for improvisation. Local drivers read the sand, know which tracks are passable after rain and carry recovery gear. Every year, people who try it alone in an unsuitable car get stuck, lose the track or break down far from help. Our advice is simple: drive yourself to M'Hamid if you like, then hand over to a professional. If you are planning a self-drive trip in the south, our guide to car hire in Ouarzazate explains insurance and which roads a standard car can handle.

Desert camps in Erg Chegaga

All accommodation in the erg is in camps (bivouacs) set among the dunes, usually with a few kilometres between them. They range from simple nomad tents with shared toilets to comfortable camps with private bathrooms in each tent. Most work on a half board basis: dinner, a night in a tent and breakfast, with the 4x4 transfer from M'Hamid sold together or separately.

Before booking, ask clearly:

• whether the 4x4 transfer from M'Hamid (and back) is included, and where you meet the driver;
• whether toilets and showers are private or shared, and whether there is hot water;
• how the camp is powered (usually solar) and whether you can charge a phone;
• what blankets or heating are provided in winter, when nights get cold;
• whether a camel ride is included or optional, and for how long.

Mobile coverage is weak or absent in much of the erg. Tell someone your plans, and do not count on your phone for navigation or messages once you leave M'Hamid.

What you do there

Life in the dunes is slow, and that is the point. Typical activities are a sunset walk or camel ride to a high dune, dinner around the fire with music from the camp staff, stargazing, and an early climb for sunrise. Some camps offer sandboarding or longer camel treks. Multi-day camel treks from M'Hamid to Chegaga also exist, for those who have the time and like walking.

Lake Iriqui and the Iriqui National Park

West of the dunes lies the vast flat depression of Lake Iriqui, the heart of the Iriqui National Park. The park was created in 1994 and covers about 123,000 hectares across the provinces of Zagora and Tata, between the Draa and the southern foothills of the Anti-Atlas. Its listed wildlife includes dorcas gazelles, houbara bustards, Barbary sheep and oryx, though you are far more likely to see lizards and birds than large mammals.

Do not expect a lake. The Draa used to feed it, but its waters are now held upstream and used for irrigation, partly through the El Mansour Eddahbi dam just outside Ouarzazate, and repeated droughts did the rest. For most of the last decades Iriqui has been a dry, cracked plain where mirages shimmer in the heat, once part of the Paris Dakar rally route.

Occasionally nature reminds everyone what it was. After exceptional rains in September 2024, satellite images published by NASA Earth Observatory showed water filling the lakebed for the first time in many years. When the bed is wet it turns to deep mud, and drivers must take longer rocky detours around it. Ask your driver about current conditions.

The Foum Zguid return loop

Instead of returning to M'Hamid, many itineraries cross the desert west to Foum Zguid, which turns the trip into a loop and avoids driving the same road twice.

• The piste: about 80 to 90 km from the dunes to Foum Zguid, generally 3 to 4 hours by 4x4, crossing or skirting Lake Iriqui. It is rougher and more isolated than the M'Hamid side, with no fuel and long stretches without mobile signal.
• The road back: from Foum Zguid, a paved road climbs north to Tazenakht and rejoins the N10 to Ouarzazate. The whole road section is roughly 160 to 175 km, about 3 hours. Tazenakht is known for its carpets; see our guide to Taznakht and its carpet cooperatives if you want to stop.
• Logistics: the loop works best with a private driver who takes you all the way from Ouarzazate and back. If you drove yourself to M'Hamid, your car is on the wrong side, so the loop rarely suits self-drivers.

Coming in from Foum Zguid and leaving via M'Hamid works just as well. Either way you see two very different deserts: the dunes and the immense emptiness of Iriqui.

How many days do you need?

Erg Chegaga is not a day trip from Ouarzazate. Even two days is tight, because you would spend about 7 hours in a vehicle each way. These are the plans that work.

Three days, the comfortable minimum

1. Day 1: Ouarzazate to Zagora or M'Hamid through the Draa valley, with stops at Agdz, the palm groves and Tamegroute. Night in Zagora or M'Hamid.
2. Day 2: Morning piste to Erg Chegaga, via Oum Laalag. Afternoon in the dunes, sunset, night in a desert camp.
3. Day 3: Sunrise on the dunes, then either back to M'Hamid and up the N9 to Ouarzazate, or west across Lake Iriqui to Foum Zguid and back via Tazenakht.

Two days, possible but rushed

Leave Ouarzazate at dawn, reach M'Hamid early in the afternoon and arrive at camp before sunset. Return the next day after sunrise and get back to Ouarzazate in the evening. It works for travellers short on time, but most of the trip is spent driving.

Four days or more

With an extra day you can sleep two nights in the dunes, add a camel trek, or spend a night in the Draa valley on the way back. This is the relaxed version, and the one we recommend if you have the time.

Best season for Erg Chegaga

The best months are October to April. Days are warm and pleasant, and the light is beautiful. From November to February, nights in the dunes can drop close to freezing, so bring proper warm layers even if the afternoon felt like summer. Spring can bring days of sand wind that blur the horizon.

From May to September, the desert is extremely hot: temperatures above 45°C are possible in high summer, the piste becomes exhausting and camps may be quieter or partly closed. If you only have a summer slot, Merzouga or a shorter trip in the Draa valley is usually the wiser choice. For month by month detail on the whole region, read our guide to the best time to visit Ouarzazate.

M'Hamid hosts the Taragalte festival, a celebration of nomadic culture with music and camel races held in the dunes, usually in autumn. Dates change from year to year, so check before planning around it.

Practical tips for the trip

• Passport: carry it at all times. There are checkpoints near the border area and your driver may need to show it.
• Cash: take dirhams from an ATM in Ouarzazate or Zagora. Card payment is rare in M'Hamid and unknown in the camps.
• Fuel: if you drive yourself, fill up in Zagora. There is no fuel on the piste.
• Water and snacks: bring more water than you think you need, especially outside winter.
• Clothing: a warm jacket for the night, a scarf or cheche against sun and sand, sunglasses and closed shoes.
• Electronics: a zip bag protects cameras and phones from fine sand; a power bank helps where charging is limited.
• Health: the piste is very bumpy. Tell your driver in advance if you have back problems or are pregnant.
• Drive in daylight: the N9 is good, but animals and unlit vehicles make night driving risky.

Starting and ending in Ouarzazate

Ouarzazate is the logical base for Erg Chegaga: it has an airport, car hire, ATMs and drivers who do the Draa valley run every week. It also makes sense to spend a night here before leaving, so you can start early with a full tank, and another after returning, when a hot shower and a washing machine for sandy clothes feel very welcome.

At Residence Chay, the two-bedroom apartments have an equipped kitchen, air conditioning and a washing machine, and the free guarded parking is useful if you leave a car behind while a driver takes you south. The reception can help arrange a driver for the desert. To fill the days around the trip, see our two or three day Ouarzazate itinerary.
