We enjoyed our lunch at The Rim restaurant at the Volcano House Hotel in Volcanoes National Park (overlooking the Kīlauea crater).
My wife and I took the tour and had a great time! The tour van—which was in excellent condition and had big windows—arrived on time. The tour was well-organized and had a great set of stops. David gave great explanations of everything we were seeing. We had plenty of time at each stop and never felt rushed. We enjoyed our lunch at The Rim restaurant at the Volcano House Hotel in Volcanoes National Park (overlooking the Kīlauea crater). David had earlier given us a number of choices off the menu which he called into the restaurant so our food was ready shortly after we sat down. The cost of the lunch is included in the tour fee. We were lucky that there was visible activity at Kīlauea while we were there. Even during the current period of activity (since 12/2024), not nearly every day has flowing lava like we saw today. The view would still have been pretty great even without that though.

Awesome adventure!
We couldn’t have made a better choice!!! Definitely the guides know their stuff, from history of the island and its people to the geological topics that kept me entertained throughout the trip. We just about went around the island in vip style, the guys were well known everywhere they took us as well as knew their way. Will recommend it to a few friends that are planning to visit the island, it’s a must in your itinerary and couldn’t have made a better choice in tour guide services

Will do again with them next time in Hawaii big island.
We did the volcano tour and it was enjoyable! Very small group, only 4, which was a plus. David was knowledgeable and he entertained the atmosphere. OK lunch provided . Snake and drinks also available throughout the day. Will do again with them next time in Hawaii big island.

Great knowledge of the area and everything about the volcano.
Went on a day tour to volcano with Grant. He had great knowledge of the area and everything about the volcano. It was definitely a 5 star service! One of the best tour I’ve had. Totally worth it.

As a geologist, his incredible knowledge about the island, natural phenomena and history was like having a documentary rolled into our vacation day.
Eric lead a private tour for family of four in his luxurious and spacious van and gave us one of the most memorable experiences of our travels! As a geologist, his incredible knowledge about the island, natural phenomena and history was like having a documentary rolled into our vacation day. We ate that up, asking him lots of questions and testing his knowledge. He passed with flying colors! When my daughter was confused about the difference between the Caldera and the additional craters, he explained it in multiple different ways until she understood it. Within one action-packed day, we covered almost everything listed on their website as typical top destinations, in addition, we did the hike down to the crater (must see!!!) and Thurston lava tube. He also arranged lunch with a caldera-side view. He was super flexible with our interests and change of plans, very thoughtful and funny, and an excellent driver, including on narrow roads, zero light, and sheets of rain. His van was even stocked with raincoats, if it wasn’t for this, we would not have been able to hike down to the crater. The tours are pricey, but it’s absolutely the best in terms of high-quality education and top notch service. We’ve been sampling private tours around the world over the years, highly recommend.

On time pick up, knowledgeable/friendly guide.
On time pick up, knowledgeable/friendly guide. The coffee tour was short but enough to understand most of the process. It would have been nice to stop for malasadas before the black sand beach stop to pick up snacks. The drive from the black sand beach to volcano was long and snacks would have been great. (My only complaint). Lunch at volcano restaurant was a highlight. Van was comfortable and I feel it was a very good value. I would recommend.

Jeanette P
I would definitely recommend him and his tour for anyone wanting to learn more about volcanoes and local culture as well as Hawaii history!
Erik was very professional, informative and engaging. His use of his education and the former positions he held made him a very credible guide. I would definitely recommend him and his tour for anyone wanting to learn more about volcanoes and local culture as well as Hawaii history!

We went through multiple ecosystems and learned more than I could possibly remember about the geology of the island and the Hawaiian islands in general.
My husband and I took the Volcanoes National Park tour. It stopped at quite a few places along the southern and south-eastern parts of the island as well as allowing you to experience Saddle Pass and views of Mauna Loa and Mauna Kea. We went through multiple ecosystems and learned more than I could possibly remember about the geology of the island and the Hawaiian islands in general. The trade off is not having time to hike through Volcanoes National Park if you want to do that, but we preferred a chance to witness the diversity we did and not having to drive. We stopped for a good meal that had a vegan option for me (green salad), which our kosher friends were able to eat as well. The coffee we sampled at the Heavenly Hawaiian Kona Coffee farm was fabulous! Our driver David and the people at the coffee farm were kind and extremely knowledgeable. Geo Tours was organized and kind enough to pick us up at the apartment we were renting. All in all a great day!

Dave was a great guide. Very informative tour. I really enjoyed the geological aspect and lots of information on how the islands were formed and keep growing. Many interesting stops along the way including a walk through a lava tube. Very cool! Great experience!
