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!!!

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.

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

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.

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!

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.

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!

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!

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.
