If you are in the area do not miss this. If you are not in the area then go to the area. A great bunch of guys. We were the only two people the day we went. We had 4 guides to drive us and take us around. Nothing was too much trouble for these people. We drove a Mercedes army truck up a muddy trail to start the adventure. Then we zip lined, were dropped into beautiful fresh water pools from the zip lines and rapelled down rock faces. It was fantastic fun and the pictures they took were awesome. A must do in Costa Rica.
