Our volcanoes your with tour guide Derek was very memorable. The tour spanned approximately 13 hours and covered pretty much the perimeter of the Big Island. Our group was small, consisting of 11 people, including my wife and I. The van was very comfortable, and our tour guide Derek was superior. Derek offered commentary throughout the tour via overhead speakers in the van. His Nuggets of island history and scenic wonders was very enlightening. A bond was formed amongst the tour members, with the help of Derek. From the Kona coffee farm, to the Punalu'u bakery, to the black sand beach, the Kilauea volcano caldera, lunch and dinner, and a stargazing spectacular, Derek managed the entire tour with unmatched expertise. My wife and I would recommend this tour to anyone, and if we were to return to the Big Island, we would recommend the Wasabi volcanoes tour, and especially Derek as the tour guide of record.
