Trips Depart whenever we have a truck loaded with 4-8 passengers. All trips require a minimum of 4 paying adults. No deposit is required however, if tickets aren't purchased 1/2 hour before departure, tickets will be sold to those on standby. During peak season tickets should be purchased 45 minutes prior and reservations should be made a day in advance. Fun and Safe For All! Our Fleet of Suburbans are enclosed and air conditioned for a comfortable ride over the mountains of sand. Each vehicle holds 7-9 passengers.
