The overnight trek gets you into the dunes for the evening and out again after breakfast, which is enough for most people. This version gives you the whole day as well, and that changes what you see.
With a full day you can reach parts of the erg that the short trek never gets near, stop at a nomad family still living in a tent on the stony margin west of the dunes, and take in Khamlia, the village south of Merzouga settled by descendants of people brought north across the Sahara, where Gnaoua music is still played daily rather than staged for coaches.
You are back in the sand for the sunset, the camp, dinner and the night, and ride out the following morning.
Start in the morning from the edge of Merzouga. The first leg heads out along the western margin of the erg, where the sand meets the stony hamada and the ground is firm enough for the camels to make good time.
There is a stop at a nomad camp. A number of families still live out here in black tents, moving with the grazing, and the visit is short and informal: tea, and a look at how a tent is put together and taken down. It is not a set piece, and the family are not performers.
Continue south to Khamlia, a village of a few hundred people whose families came north across the Sahara generations ago. Gnaoua music here is played on guembri and metal qraqeb, and it is a living tradition in the village rather than a show. Sessions are informal and you sit with the players.
Lunch follows, taken in shade during the hottest part of the day. In summer this is a genuine rest stop; between June and August the middle of the day in the erg is not a time to be moving.
As the heat drops the camels head back into the sand, this time into the higher interior of the erg. The crests here run above 100 metres and the troughs between them are wide and completely enclosed; nothing is visible in any direction except sand.
You reach a high crest for the sunset, then drop down to the camp as the light goes. Tea on arrival, then dinner in the main tent, a fire outside and drums afterwards. The sky over the erg has no competition from any settlement.
Up before dawn for the sunrise from the crest above the camp, a short climb through soft sand. The dunes are cold, still and unwalked at this hour.
Breakfast at the camp, then the camels are loaded for the ride back to Merzouga, arriving in the morning. A 4×4 return can be arranged instead on request.
Around four hours in total, split across the morning and late afternoon legs, with the middle of the day off the animal for Khamlia and lunch. It is not four continuous hours.
No. These are families genuinely living out on the margin of the erg with their herds. The visit is brief, involves tea, and is arranged through people the handlers know.
A tradition brought north across the Sahara, played on a three-stringed guembri and iron qraqeb castanets. Khamlia is one of the places where it is still part of village life rather than a tourist performance.
Between June and August the middle of the day is genuinely hot, which is why the itinerary puts Khamlia and a long lunch in the shade at that point. The riding is done in the morning and late afternoon.
If you would rather shorten it, the overnight trek covers the sunset, camp and sunrise without the daytime section. This version is for people who want the erg itself rather than just a night in it.
Sun protection and a hat for the day, a warm layer for the night, a torch, and an overnight bag. Everything else can be left at the departure point.
The standard overnight trek shows you the dunes at their two best hours and nothing in between. This one gives you the day as well: the nomad families on the stony margin, Gnaoua music at Khamlia played by the village for itself, and the deep interior of the erg where the crests run over 100 metres and there is nothing to see in any direction but sand. Then you still get the sunset, the camp and the sunrise.
