Our family of four wanted a fun outing in addition to hiking and sight-seeing, and so glad we did the Courthouse Loop 1/2 day ride with Rim Tours. Bill and Russ were the guides and they were excellent - personable, helpful, and set the right tone. Bill provided a short but very good set of instruction and guidance, and even for me, an experienced road rider, I found it very helpful, as did my wife, a mountain bike novice. With two guides we were able to split into two groups to accommodate different levels of skill and fitness. I was pleasantly surprised by the quality of the bikes they provide. Letting them handle picking out the route and providing the bikes was worth it.
