My friends and I were in Reno and wanted to kayak down the Truckee river. This outfit would take you about 5 mi upriver and drop you off with a guide. The guide, Tim, was not much of a guide. I wish that we had done the unguided trip, which was much less expensive.
My issue is with Tim, not with this company. Tim was in a raft with 2 girls and there were about 5 single kayakers. A guide is supposed to be there for Safety but Tim went so far ahead in the raft that when one of the kayakers fell out, it was up to the rest of us to help him get back into the kayak! Tim also said a couple of inappropriate things on the bus ride to the drop off point.
The kayaking itself was great and would not hesitate to do this again with Sierra Adventures - but I would opt for the unguided tour.
