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.

Very knowledgeable on the geology and the history of the islands, and made the trip enjoyable and interactive.
David was a consummate professional. Very knowledgeable on the geology and the history of the islands, and made the trip enjoyable and interactive. It was a very long day for him and he was gracious and polite. This was a great tour. Call him Superman!

Felt like we saw the best of the island by the time we were finished.
This tour was awesome and the highlight of visit on the Island of Hawaii. Erik gave insights to the island’s geology as we went along the tour, which was very interesting. He also took us to some hidden gems off the typical tour route to see some really beautiful parts of the park. We started the day at a coffee plantation, then a black sand beach, volcano National park, lava tube and the finished the day rainbow falls. Felt like we saw the best of the island by the time we were finished. The hot lunch, snacks, and multiple drink options were a nice touch. Definitely recommend Hawaii Geo Tours.

If you're staying in Kona and want a world-class experience, book David. He truly made our vacation unforgettable!
Our family (including two teenagers, ages 17 and 12) had an absolutely incredible day exploring Volcanoes National Park with David. If you are looking for a guide who combines deep scientific knowledge with a genuine passion for the island, David is the gold standard. His background in geology and botany turned the landscape into a living storybook. He didn't just show us the sights; he explained the 'why' and 'how' behind the volcanic formations in a way that kept both of our boys totally engaged. Beyond his superior expertise, David is just a fun-loving person to be around. He shared wonderful stories that gave us a real feel for the culture and history of Hawaii, and he went above and beyond to tailor the day so we could truly appreciate the most dramatic views. He made what could have been a long day of driving feel like an effortless, awesome adventure. If you're staying in Kona and want a world-class experience, book David. He truly made our vacation unforgettable!

The sites are beautiful and we got to see a few places that we probably never would have gotten to see had we not gone on this tour.
We had such a great time! Dave was our tour guide, and he was very entertaining and a wealth of knowledge. The sites are beautiful and we got to see a few places that we probably never would have gotten to see had we not gone on this tour. We went to a coffee farm, the Volcanoes National Park, the lava tubes, Rainbow Falls, and lots more. It was a long day, but worth every second. Very highly recommend going on the Volcano National Park Adventure!

Great food, wine tasting and the locations were amazing.
This tour was the highlight of our trip. Eric and Leilani treated us like royalty. The places we visited were awesome. Great food, wine tasting and the locations were amazing. Eric is a former geologist so we learned a lot of new things. I totally recommend that you book an adventure with them.

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.

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!

We highly recommend this tour to anyone wanting a truly memorable and well-rounded Hawaii experience!
We had a fantastic time on our Hawaii Geo Tour with Eric — even with the rain and crazy fog! Eric kept the experience fun, engaging, and full of incredible information. We also loved so many of his recommendations for places to visit and places to eat; they really helped us make the most of our trip. If you’re worried it’s going to be a “boring rock tour” or involve too much walking, don’t be! The tour is well-paced, exciting, and gives you the chance to see a huge portion of what the island has to offer without feeling overwhelmed. We highly recommend this tour to anyone wanting a truly memorable and well-rounded Hawaii experience! 🌺

Hawaii Geo Tours are the best!
Wow! Fantastic tour of the erupting volcano!!! The guides are geologists and explained so much about the volcano and how all the Hawaiian islands were created. The pictures I got during the day, and especially at night were incredible! The food and winery tasting were good too. I’ve done this tour twice in the past year and recommend it highly! I wish I could give more than 5 stars!!! 🤙
