We went through multiple ecosystems and learned more than I could possibly remember about the geology of the island and the Hawaiian islands in general.
My husband and I took the Volcanoes National Park tour. It stopped at quite a few places along the southern and south-eastern parts of the island as well as allowing you to experience Saddle Pass and views of Mauna Loa and Mauna Kea. We went through multiple ecosystems and learned more than I could possibly remember about the geology of the island and the Hawaiian islands in general. The trade off is not having time to hike through Volcanoes National Park if you want to do that, but we preferred a chance to witness the diversity we did and not having to drive. We stopped for a good meal that had a vegan option for me (green salad), which our kosher friends were able to eat as well. The coffee we sampled at the Heavenly Hawaiian Kona Coffee farm was fabulous! Our driver David and the people at the coffee farm were kind and extremely knowledgeable. Geo Tours was organized and kind enough to pick us up at the apartment we were renting. All in all a great day!

One of the best tours ever
What an excellent way to get to know the Big Island and learn about its unique place on Earth. Our tour guide Eric picked us up on time at our rented villa along with a number of other visitors and we proceeded to spend one of the better days on a tour of the island. Eric is one of the proprietors of the tour, is a degreed geologist and is truly an engaging and friendly person. The tour was excellent which combined both interesting sights and a tremendous amount of local knowledge about lava flows and local history. To say that this was worth the day spent would be to put it mildly. Even at twice the price, I would happily do this again and recommend the tour to anyone.

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!!! 🤙

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.

My boyfriend and I have been in Hawaii for over two weeks and done many tours here, but this by far was our favorite one.
DEAR READER- STOP RIGHT NOW! IF YOU ARE ON THE BIG ISLAND- YOU NEED TO TAKE THIS TOUR!!!!! BOOK IT. David was an INCREDIBLE tour guide. My boyfriend and I have been in Hawaii for over two weeks and done many tours here, but this by far was our favorite one. We learned so much. David was so incredibly kind and informative. You could tell he genuinely cares about the volcanos, the island, the people and animals who live here, and the guests on the tour. He took the time to get to know everybody and he was SO GOOD with names and remembering people. He knew amazing details and stories about the island and the volcano and the coffee farm. My boyfriend is absolutely fascinated with volcanos and said it was his “once in a lifetime tour.” It was the perfect amount of guests too. Not too crowded. Amazing stops, each one was worthwhile. And- a very comfortable and clean van. DID YOU BOOK??? DO IT!

Well worth the time and money
David was an outstanding host and tour guide. He was very knowledgeable and entertaining. I highly recommend this tour. You will see a ton, learn a lot about the island and enjoy a delicious lunch.

Tana K
Was prompt and delivered us back on time.
It was a great tour! Took lots of pics! Zane was very informative all through out the trip. Was prompt and delivered us back on time. It is an all day adventure so be prepared for a long day. He did prepare snacks and drinks for us and umbrellas or parkas if you need it. The bus was very clean and comfy.

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.
