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.

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.

I would definitely recommend him and his tour for anyone wanting to learn more about volcanoes and local culture as well as Hawaii history!
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!

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

GEO TOURS was easy to work with, exceptionally attentive response time to communication all questions prior to our trip.
GEO TOURS was easy to work with, exceptionally attentive response time to communication all questions prior to our trip. The cost of ANY tour and ALL tours are high in Hawaii- but for what you receive on this trip I felt that they were priced correctly in their marketplace. We stopped at interesting locations along the way: All of the ones they indicated and nothing felt like a big sales pitch anywhere which was great. If you are traveling with children be aware this is a LONG all day tour. If you're a car-sick kinda person like me - come prepared! I hate being loopy, but that's what I sacrifice to be with our whole group. Take your Bonine people! Our tour guide for our party of nine was Dave. Great guy! Knowledge, kind, engaging and obviously done this sort of thing a lot. I was a bit bummed we didn't get one of the actual geologists (as we were traveling with my brother who IS a geologist and when booking with Erik I mistakening thought he would be our tour guide that day. I knew it wasn't a private tour, and now I kind of wish I would have booked a private tour. We were so fortunate that the family we traveled with had delightful children and easy to combine our group with. What I realize in hindsight, is that it would be worth paying the price for private and having a little more wiggle room for our personal group. We were four adults and five siblings; 20,17,15,11,9. Dave on his own as a travel guide and driver was helpful, efficient, a gracious island host and very easy to be around. He didn't make up anything and was not grandiose; as some guides tend to be know-it-all-junkies. THANKS Dave for your kindness to our whole family. Thank you GEO Tours. The family voted you as their favorite vacation activity.

We enjoyed the tour with Hawai’i GEO tours. Our guide was exceptionally knowledgeable, professional, and personable, and his passion for Hawaii and its history was evident throughout the tour. He provided a wealth of insightful information while keeping the experience engaging and enjoyable. Although the excursion lasted approximately 11 hours from pickup to drop-off, the itinerary was seamless, well-coordinated, and thoughtfully organized from start to finish.

Geo adventure family trip for the win!
David has a vast knowledge of so much of the island it’s amazing and he charmed us with a ton a factoids the whole day. Highly recommend if you are short on time on the island but want to see as much as you can in little time.

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.
