Thirty four million years ago, the entire area used to be under an ancient sea and you’ll come across plenty of fossils. Since it’s open year round, this is an attraction you don’t want to miss. With Off-Road Adventures you can rent an ATV so that you can join in on all the fun in the desert hills. If you have a 4×4 vehicle, you can make this an all-day event by grilling and hanging out with friends or family.
