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.

Excellent all-day experience of many Big Island sites with an expert geologist tour guide - Zane picked us up early in a very nice small custom bus. His geological and island knowledge were amazing. The tour through Volcano Natl. Park was outstanding. It was basically 12 hours to go over much of the island. We've been on many guided tours around the world; this was one of the very best, and I highly recommend it. Thanks, Zane!

Bottom line: you are seeing a volcano even if it decides not to show off!!! - During our tour we enjoyed wonderful insightful history about the island and Volcano facts…..excited to see the volcano and its smoke…..that in itself would still make this a great tour….just being there!!!!!!…BUT we were blessed to see Kilauea spew her “fountain”……all during a wonderful sit-down lunch…….Erik supplied us with flexible “stay and enjoy” time and gave us such interesting facts about what we were seeing! This will remain a “once? in a lifetime experience……..highly recommend this tour company……great communication and pick-up/return……

Amazing Volcano & Island tour with Hawaii Geo Tours - My husband and I took a Volcano Tour with Hawaii Geo Tours and it was such an incredible experience! We enjoyed the beautiful island & were educated way beyond our expectations! Zane is a retired geologist and has so much knowledge of the volcanoes, landscape and climate of Hawaii that it's amazing! (along with a lot of other fun facts) His life experiences and love of volcanoes contributed to everything he shared with us! I can’t imagine any other guide that would’ve been able to give us so much information about Hawaii! He was professional, knowledgable, friendly and willing to take photos and answer any questions that anyone had. It was a long day but so worth it if you want to see all the sights that Hawaii has to offer without having to plan out an itinerary of things to see and to drive to all of the sights. It was a small group and in a nice, comfortable and clean Mercedes van. Zane also provided lots of drinks and snacks to eat at the stops we made. We stopped at Heavenly Hawaiian coffee farm and we learned a lot about Kona coffee. We tasted 5 different varieties of Kona coffee, purchased some coffee beans in their gift shop and joined their coffee club too! The lunch at The Rim restaurant, which is also included in the price of the tour was the perfect stop instead of having to pack a lunch. We both enjoyed the Volcano Burgers with the added bonus of a view of the Kilauea caldera while we sat and ate. We went to Punaluʻu Beach which is a Black Sand beach and saw turtles, went to the Lava tunnel and made several other stops along the way! We even got to stop at a local farmer’s market and picked up a few gifts. Zane bought all of us a Hawaiian sweet, tiny banana to try too! (Not sure what the name of it was called) I would highly recommend going on this tour if you want to efficiently experience all that you can in a day and learn all about the island of Hawaii and it’s stunning volcanoes! It was one of the best tours we have ever gone on because of Zane! Book this tour! I promise, you won’t regret it! :)

Best informative and fun tour of Hawaii - My husband and I took a Volcano Tour with Hawaii Geo Tours in October 2025 and it was such an incredible experience! It was a very informative and fun day! Not only were we able to enjoy the beautiful island but were educated way beyond what we had expected! Zane is a retired geologist so his knowledge of the volcanoes, landscape and climate of Hawaii was amazing! (along with a lot of other fun facts) His life experiences and love of volcanoes contributed to everything he shared with us! I can’t imagine any other guide that would’ve been able to give us so much information about Hawaii! He was professional, knowledgable, friendly and willing to take photos and answer any questions that anyone had. It was a long day but so worth it if you want to see all the sights that Hawaii has to offer without having to plan out an itinerary of things, figure out where to eat or how to navigate the roads to get to places. It was a small group and in a comfortable, clean Mercedes van. Zane also had lots of drinks and snacks to eat at the stops we made along the way. We stopped at a Kona Coffee plantation and we learned a lot about Kona coffee. We were able to taste 5 different varieties of Kona coffee and purchased some coffee beans in their gift shop. We liked it so much that I ended up joining the coffee club once we got home! The lunch at The Rim restaurant was also a nice stop instead of having to pack a lunch. We both had the hamburger and French fries and it was very good . The view of the Kilauea caldera was also an added bonus while we sat and ate. We went to a Black Sand beach and saw turtles, Lava tunnel and many other stops along the way! We even got to stop at a local farmer’s market and got a few things. Zane bought all of us a Hawaiian sweet, tiny banana to try too! (Not sure what the name of it was called) I would highly recommend going on this tour if you want to experience all that you can, very efficiently and learn all about the island of Hawaii and it’s stunning volcanoes! It was one of the best tours we have ever gone on because of Zane! Book this tour! I promise, you won’t regret it! :)

Amazing Volcano Island Tour - I had an amazing experience one the Volcano Adventure Tour. David our guide was very knowledgeable about Hawaiian culture and history, he shared so many stories about the island and Hawaiian culture. The views were stunning. David really took care of our group, paying attention to details, asking guests if he could take pictures, calling each guest by name and checking in on us throughout the tour. I highly recommend this tour. You will see a great portion of the Big Island.
