Yes, a 3-day tour is an ideal amount of time to experience the Sahara Desert. While the first day is primarily spent traveling from Marrakech to Merzouga, the second day allows for desert exploration, including a camel trek to the Erg Chebbi dunes and an overnight stay at a desert camp. Although brief, the tour provides a comprehensive introduction to the Sahara's breathtaking landscapes, mesmerizing sunsets, and unforgettable starlit nights.
