Bolt says Geo Tour Big Island
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!

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.

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!!! 🤙

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.

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!

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.

One of the best tours ever
What an excellent way to get to know the Big Island and learn about its unique place on Earth. Our tour guide Eric picked us up on time at our rented villa along with a number of other visitors and we proceeded to spend one of the better days on a tour of the island. Eric is one of the proprietors of the tour, is a degreed geologist and is truly an engaging and friendly person. The tour was excellent which combined both interesting sights and a tremendous amount of local knowledge about lava flows and local history. To say that this was worth the day spent would be to put it mildly. Even at twice the price, I would happily do this again and recommend the tour to anyone.

Was prompt and delivered us back on time.
It was a great tour! Took lots of pics! Zane was very informative all through out the trip. Was prompt and delivered us back on time. It is an all day adventure so be prepared for a long day. He did prepare snacks and drinks for us and umbrellas or parkas if you need it. The bus was very clean and comfy.
