Trip Advisor Reviews

"Marcel arrived on time, in a great vehicle. His knowledge and persona made for a really great day out."


"This was my first time on a mountain bike tour. I had a blast with Marcel as my guide. We rode a half day tour at China Camp Park on a Santa Cruz Bronson.

The service and equipment is top of the line and a value for the thrills these tours deliver. I really appreciate how Marcel took the time to not only custom fit the suspension to me but also taught me so much about the mechanics of a full suspension bike as well as some really useful riding tips.

I also really appreciate how Marcel basically takes care of everything from coffee, water, snacks to even taking pictures!

I truly felt pampered and spoiled with all the tour had to offer. You can hardly tell the miles you are putting in with how these guys set you up."
