This is an excellent all day trip. The guide was extremely knowledgeable and personable. The highlight is seeing the active volcano at night with orange glowing lava, very cool to see and the best reason to take this tour. The group on the tour was only 5 in number so it was truly personalized service. Other points of interest were waterfalls, walking through old lava fields and lava tubes, the Mauna Loa macadamia nut orchards and visitor center bought lots at their store, an orchid establishment, the Japanese gardens loved the Banyan trees, visiting Big Island Candy for free samples of candy and Kona coffee bought lots there too and visiting beautiful beaches. Not physically strenuous so the tour is suitable for anyone.
