We had a great experience with Sahara Buggy. It was a fun and exciting way to really explore the dunes, and to see how vast the desert is. Safety helmet and a bottle of water were provided. They were very accommodating, taking us last minute for a dune buggy ride. Our guide was great, took some nice pictures of us and let us mount our GoPro to the back of his quad to get videos from a different vantage point. Price was reasonable. Definitely recommend including this in your Erg Chebbi experience!
