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

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.

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 had an amazing experience with Hawaii Geo Tours!
We had an amazing experience with Hawaii Geo Tours! Our guide, David, was incredibly knowledgeable, professional, and friendly—you can truly tell he loves what he does. He’s a wealth of information, and even though the tour is long (about 11 hours from pickup to drop-off), everything ran smoothly and was very well organized. David picked us up right from our hotel, and we got to see so much of the Big Island: a local coffee farm, a stunning black sand beach, a delicious lunch at the famous Volcano House, walking through lava tubes, and down to the coast where the road ends due to lava flow. We also stopped at the Big Island Candy Company and finished the day at beautiful Rainbow Falls. It’s a long day, but the trade off was not feeling rushed. Our group included one boy 6 years old who was naturally antsy but thankfully well behaved, so families with young children should consider the long stretches in the van. That said, it was still a wonderful experience. This tour is a must-do if you’re new to the Big Island. It’s an excellent way to see a wide variety of highlights while learning about the island from a true expert.

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!!! 🤙

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!

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.
