What a great family activity!
Not for small children but AWESOME for the 18 and up crowd. I went with my 18 and 22 year old and we spent several hours exploring Red Rock Canyon. The motorized bikes really make it easy for friends or family members with different fitness levels to have a great time together. The owners, Laurent and his wife, gave us a tutorial and ensured that we were safe and comfortable before setting out on our own. They provide all the safety equipment...even bottles of water.
We will definitely do this again soon! HIGHLY RECOMMEND
