Excellent tour!
David was a wonderful guide! He was very knowledgeable, courteous and witty. The volcano and its history are so fascinating, as well as the coffee farming. Excellent tour!

We highly recommend this tour to anyone wanting a truly memorable and well-rounded Hawaii experience!
We had a fantastic time on our Hawaii Geo Tour with Eric — even with the rain and crazy fog! Eric kept the experience fun, engaging, and full of incredible information. We also loved so many of his recommendations for places to visit and places to eat; they really helped us make the most of our trip. If you’re worried it’s going to be a “boring rock tour” or involve too much walking, don’t be! The tour is well-paced, exciting, and gives you the chance to see a huge portion of what the island has to offer without feeling overwhelmed. We highly recommend this tour to anyone wanting a truly memorable and well-rounded Hawaii experience! 🌺

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.

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!!!

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.

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.

David was a consummate professional. Very knowledgeable on the geology and the history of the islands, and made the trip enjoyable and interactive. It was a very long day for him and he was gracious and polite. This was a great tour. Call him Superman!

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

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.
