Great tour for families! - Highly recommended, the van was clean and spacious. David our guide is knowledgeable in all aspects volcanos, he exudes passion for the islands. It takes the full day, but you really get to see a lot of things in one day. The included lunch was at a restaurant, also very good. We always felt secure and in good company.

Hawaiian volcano tour - This trip is an all day event with much to see. At this time of year(Nov/Dec), warm clothing isn't necessary, but you should expect rain. It's a long drive, you'll be sitting for extended periods. Be prepared for much beauty. Our guide was very knowledgeable, and offered so much information about the island, and the weather changes, and some historic events. David was fabulous as a tour guide.

Very Fun Tour - The tour was awesome! We went around the island and stopped at some cool places. Some of the places we went to were a lava tube, volcano national park, and a black sand beach with a seal and turtles. There was not too much walking and our tour guide David was great. He was very knowledgeable and told us about the place we went to.

Fun on the Island of Hawaii with Hawaii Geo Tours - This was a wonderful experience. Zane was absolutely the best tour guide anyone could have. His knowledge and insights made the trip educational and fun! He took us to places where most tour companies will not go and he was flexible based on the weather. I highly recommend Hawaii Geo Tours and Zane!!!

Fabulous tour - This was a fantastic tour. We debated doing it ourselves and even rented a car to do so but at the last minute decided to go on this tour. David was a wealth of knowledge, it was extremely interesting, a very long day, but a very comfortable van. We are so glad we left the driving to him and highly recommend this tour

Fantastic day - The tour was amazing! Our guide, Dave, was knowledgeable, friendly, funny and very interactive with the guests. The Island is beautiful and we’ve learned so much. Thanks to Dave and Geo Tours for a wonderful day!

First Time in Hawaii - This is our first time in Waikoloa and I have to say that this is the best tour I’ve ever experienced. You have a great guide by the name of David Human, who does a great job of narrating as he drove us from one end of big island to the other. From the coffee farms, the volcanoes, and rainbow falls. I give this tour a 10 out of 10 and is a must for all who travel to Waikoloa.

Fantastic Trip! - David gave us an amazing day around Big Island. He was so informative and went out of his way to make sure we had a memorable experience. We loved the turtles at the Black Sand Beach. Having lunch on the rim of a volcano was really cool and the food was great! I highly recommend this tour. It’s a great way to to see a large part of the island and experience all the climates in one day.

Closeup view of lightening but not volcanos - Great tour guide, but should have called it on account of huge rain storm with thunder and lightening. Volcanoes not active, but still could not even view inactive ones. Several of the venues described were closed du3 to the storm. Not owners/drivers fault….but should not have attempted due to the severe storm conditions. Credit to driver for improvising, by trying to find other points of interest. Just a really bad day to do this tour. Never offered refund or credit.

Spend your money elsewhere. - The views from inside Volcanoes National Park are the ONLY reason this tour got 2 stars. Our tour guide, Zane, talked about millionaires and billionaires and how much everything cost for the majority of the first hour. He loved mentioning his girlfriend, who he knows on the island, how much things cost inside the van and pointing out where wealthy people live and go on the island. My family booked this tour because we wanted to learn about Big Island. I will admit, this was my mistake, because we weren’t interested in a geological tour. We wanted to learn about big island culture and history. However, all that being said.. My parents could not hear much from the back of the bus, and after we asked Zane the first time.. he checked in with us to see if we could hear better. We could for a little while, but after about 20-30 minutes we couldn’t hear very well. We asked him 3 more times during the course of the day to speak louder or adjust the mic and there was no difference and he never checked in with us again. Things got a little better once we were in Volcanoes National Park. He spoke more about the history of the volcanoes, how they were formed, the different types of lava flow and the craters. But as I said before, my parents couldn’t hear much from the back. So when my mom asked a question about the differences in lava and why they looked different, she was met with a snarky attitude of “well don’t you remember the video?” Which wasn’t the last time during the day that we were met with snarky behavior or an attempt to be funny that just missed the mark. Not long after that, my mom slipped on some loose rocks out on the lava formations where he took us. The fall wasn’t bad, and she bruises easily so it looks worse than it is. But instead of being met with concern by our tour guide, like anyone would expect, Zane told her in a sarcastic tone that she couldn’t walk back by herself. He didn’t check in with her until after he got back to the van, a bit later. A very nice woman on our tour helped escort her back until I could reach her. Once Zane made it the van, one of the first things he said was “oh that’s not bad,” as I’m trying to clean up blood from where she fell. Luckily the woman who helped my mom back had bandaids, because Zane and Hawaii Geo Tours have no sort of first aid. He said they had to stop during Covid, but we’re past that now. Carry bandaids (even if you can’t administer first aid), just do better and be prepared. The rest of the tour had some pretty and cool views. We walked through a lava tube, stopped in Hilo for a farmers market and to see Banyan trees. Overall, I would skip this tour, save your money and a headache from hearing a bunch of “I did this, my girlfriend does that and this cost $xxxxx.” There were also a couple points in the tour where it felt like he was digging on the Hawaiian people. And after having an amazing tour in Maui with someone who’s connected to Hawaiian culture, I felt offended on behalf of the Hawaiian people with the way he spoke a few times.
