Sand mountain is an awesome sight when you riding straight up the face, if you have a big bore CR 500 with a paddle tire you can make it up over the top without a paddle tire you will need to find out for yourself. There are plenty of dunes to ride in so you do not have to worry about finding a great place to ride. There is not any bad places to ride and if you like hard dirt there are plenty of dirt trails and of to the side of the oasis camp groun there is a huge mountain to climb!
