The 1-hour quad ride is the short version: enough to cover ground and see the Atlas line, ninety minutes at the base in all, and back in Marrakech inside half a day.
The 2-hour quad ride goes further out, away from the tracks nearest the base, with a second stop, for two and a half hours at the base in all. If you have ridden before, this is the one that will feel worth the trip.
The quad and dinner evening puts the same two hours of riding before a Moroccan dinner on the same site, four hours in all, starting at 4 pm (5 pm in summer). Because it includes a quad, the whole evening is from age 6.
The other half-day outings put the quad inside a longer programme: a meal under a tent, a camel walk, or both. They are the same riding, wrapped in an afternoon and an evening rather than an hour.
The VIP pack starts at 4 pm (5 pm in summer) with an hour on a 350 cc quad, then adds a camel ride, tea on a dune with a 360° view, and dinner at a private table with music and a fire show. The dune is a natural dune of earth, not of sand.
