Erik was very professional, informative and engaging. His use of his education and the former positions he held made him a very credible guide. I would definitely recommend him and his tour for anyone wanting to learn more about volcanoes and local culture as well as Hawaii history!

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

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!!! 🤙

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!
