This was one of the highlights from our trip to Costa Rica. Our guide Rayner was great, picked us up and got us on our way. Once we got to the Canyon Adventure compound, he checked in with us regularly and walked us through the itinerary for the day, meals, etc. We had such a fun day zip-lining, white water rafting, riding horses and ending up in the hot spring pools. Fair warning, if you elect to do the Volcanic Mud bath at the hot springs, prepare for the smell to stick with you for days on your clothing.. Other than that, I'd highly recommend this tour, and would also recommend booking through Pininos Adventures - we also booked our ATV & Beach tour with them, and overall had excellent customer service!
