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.

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!

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

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.

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.
