From customer service, to safety, to downright friendliness, these guys have it all. We booked a last minute reservation - their website said there were none available but we called in as they suggested, and they were able to find us a time slot that day. From the moment we were greeted by our guides, Nathan and Kyle, and driver Ehu, we knew we were in for a great time. They were fun and friendly, and they engaged us in conversation for the entire trip, filling us with knowledge about the places we were in and the things we were seeing. Once at Halekea (the "White House" which is the starting point for the zip line), they filled my safety-conscious family with a great deal of confidence. They were extermely conscientious and took great attention to detail with the gear and lines, all the while keeping the nervous ones calm with their good humour. The zip-lines themselves were so much fun, and the Ohi'a forest we were in was beautiful! Nathan and Kyle encouraged us to try fun things while zipping - swinging, flailing our arms, or going "dead-man", and even giving us a good-natured bounce to the line to add to the fun - but NEVER in a way that made anyone feel uncomforable - they new each persons limits and boundaries and respected them greatly. All in all, this family of four had a super fun time and are looking forward to coming back some day to do it again.
