Amazing tour! I am not typically someone who takes tours, since I prefer to go off the beaten path, but Scott made sure we got to enjoy the adventure along the way. In a single day we went through ~6 different climate zones on the Big Island, explored volcano vents, waterfalls, gullies, beaches strewn with massive lava rocks, ate hot masaladas (Portuguese donuts, absolutely delicious), see wild goats and pigs, and probably a dozen other things I am forgetting. 100% worth-it experience, I recommend doing it on your first day, since it will give you a good idea of how much is available while you are there. Also, Scott does a great job as a tour guide, providing details about the history of every area visited, never going into the monotone drone that seems to be so common-place, and he was fantastic putting up with my irrepressible urge to run off and do my own thing at times.
