Exceptional! An absolute winner. This was my fourth trip to Hawaii, but the first to the big island. We were looking for something new and unique to this island, and this fit the bill perfectly. We did the two hour tour. Guide was informative, funny, and very knowledgeable. Physically, it is moderately demanding. Limited crawling with knee pads, which was not hard. Walking in lava rocks required all my attention (age 63 with average balance). The things we saw were breathtaking. Guide was Brian. He was great. Top end equipment. No shortcuts on quality. Heck, I even liked their upgraded outhouse!

I had a great time here solo, there was 6 of us. Gary who answered the phone, was very passionate about these lava tubes. My guide was funny and knowledgeable. I took the hour tour, was easy, couple steps, and a short ladder. I will be back in a few days to take the second tour of 2 hours since I wanted to continue!

The tour was so amazing! Mo gave us lots of background info to help us understand the geology and history of the area before taking us into the cave to explore. Highly recommend this tour when you are visiting the Big Island!

We did the 2 hour tour and I'm so glad we did more than just the Lighted Tour! Brian was a fantastic guide, very funny and knowledgeable of the tubes. He answered any and all questions and provided a lot of great information during the tour. Would highly recommend this tour for anyone looking to get a deeper experience on the lava tubes and is physically able!
