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.

We enjoyed our lunch at The Rim restaurant at the Volcano House Hotel in Volcanoes National Park (overlooking the Kīlauea crater).
My wife and I took the tour and had a great time! The tour van—which was in excellent condition and had big windows—arrived on time. The tour was well-organized and had a great set of stops. David gave great explanations of everything we were seeing. We had plenty of time at each stop and never felt rushed. We enjoyed our lunch at The Rim restaurant at the Volcano House Hotel in Volcanoes National Park (overlooking the Kīlauea crater). David had earlier given us a number of choices off the menu which he called into the restaurant so our food was ready shortly after we sat down. The cost of the lunch is included in the tour fee. We were lucky that there was visible activity at Kīlauea while we were there. Even during the current period of activity (since 12/2024), not nearly every day has flowing lava like we saw today. The view would still have been pretty great even without that though.

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!

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!
