Wonderful time with Zane - Our experience with Hawai’i Geo Tours was unforgettable, largely because of our guide, Zane. From the start, it was clear he genuinely loves what he does. Zane has a deep understanding of the Big Island and a gift for explaining it in a way that’s easy to follow and actually interesting. He didn’t just point things out—he connected the landscapes to the island’s volcanic history and ongoing changes, which made everything feel more meaningful. What stood out most was how every stop came with context. Whether it was lava fields, coastal views, or a black sand beach, he always had something insightful to share, including cultural details that added depth to the experience. Nothing felt rushed or generic. We also really enjoyed the visit to Heavenly Hawaiian. Zane walked us through the coffee process in a way that made the tasting even better. The coffee itself was excellent. Overall, this tour went beyond expectations. Zane made the island come alive, and we left with a much stronger appreciation for Hawaii than we would have on our own. Highly recommend

Volcano National Park - Our tour guide Dave was awesome. We were able to see a lot of the island and spend time in the national park was well worth it.

Incredibly knowledgeable. Well organized. Super friendly. Perfect really. - As first timers to the island, this was an incredible trip. We had Eric then David as our guide. They both shared so much about the rock formations and the island in general, and could answer every obscure question we had. Logistically it was great to be collected from Waikoloa, rather than having to meet a tour in Hilo for an early morning departure. Our small group's first stop was Heavenly Coffee - amazing! We didn't know how coffee was made, and sampling the different coffees was the perfect pick-me-up to head onto the black sands beach (with fresh donuts), then the volcanoes. Highly recommend treating yourself to the cheeseburger for lunch. The island beef was delicious. The whole trip was well organized (they even had rain jackets ready to go when the weather turned), super informative, and wonderfully friendly. Looking at the serious lack of parking in Volcanoes National Park, we were glad we chose a tour, and even happier we'd had such a brilliant day with Hawaii Geo Tours.

David was a fantastic... - David was a fantastic tour guide. He made the entire day very interesting, enjoyable, and we learned a LOT. I can’t say enough about him. If we could choose a tour guide for a future excursion, David would be our first choice. Thank you for a great day!! Wendell & Kris

Best day ever! - David H. Was a terrific guide. He was the best tour guide we have ever encountered. He shared his knowledge of the island and volcano freely and the depth of his knowledge was incredible. He was positive and friendly with everyone. He had a show and tell about the different types of “souvenirs” he had collected from the volcano, small rocks, glass shards. We had the experience we wanted and we were very happy at the end of the day. He had a nice lunch planned for the group with snacks and drinks later in the afternoon. I would do it again. If you do nothing else on the island, take this tour. You will have spent your time wisely.
