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

Great food, wine tasting and the locations were amazing.
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.

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.

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.

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!

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!

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.

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!!! 🤙
