If your looking for some offroad fun, these are the guys to contact. We had the experience of doing a tour with them in the Imperial Dunes. The owner was very friendly and educated on off-roading in the dunes. We truly felt safe on our tour. They even took the time to make sure my helmet fit properly. The actual tour was an amazing ride that definitely gave us a dune experience like no other. They also offer rentals but we went for the cheaper tours and were not disappointed. Definitely check them out!
