We decided on the fly to go on the river, but not sure what we wanted to do: kayak? canoe? raft? Showed up, didn't need reservations, we told them what we wanted, our experience level and the time we had to spend on the water and they were like "No problem! Here you go..." and got us into a canoe, telling us we could do 2 hours or 4 and we could decide once we were out on the river.
Price was excellent, and they even had a little shop where we could buy a waterproof camera, sunhat, waterproof bags, Gatorade and peanuts for snacking, etc.
Service was friendly and knowledgeable and I would recommend this outfit wholeheartedly, they made it as painless as possible for an affordable price.
