For our family of four, we rode 2 double rider ATV's and had a great time. Our group was about 15 people (a good size). Our group was small, so we were able to get to the landmarks before other tours. Our two guides, Gabi and Alex, were awesome. They made the trip 10x better. It was an awesome overall experience and the views were so cool. The natural bridge was beautiful and the natural pool was so refreshing. The helmets were very nice. The ATV's were very simple and straight forward to work; the trip had a very clear path that you are able to follow. You and your family will have a fantastic time. This company is so hospitable and helpful.
Some advice: The double rider ATV's have a storage compartment in the back, but the single ATV's don't. Bring towels if you have the option. Bring a camera because you will have many picture opportunities. Make sure you remember your drivers license if you are operating the ATV.More
