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.

Best Island Tour!
A must tour experience! Such an incredible day. What is unique about This tour, is how much you learn about the island formation and the flexibility in where he takes you! We traveled with friends and booked the VIP tour…if you can swing it, definitely put Geotours on your itinerary! Erik will not disappoint. You can see that he is passionate about the island and what he does. Mingled well with our group, lots of laughs, great energy and had a BLAST!!!

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

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.
