The Hidden Craters Hike is a once in a lifetime experience. "Hidden" is a very apt word, as we didn't see any other tourists during the entirety of the hike. We felt so honored to be able to visit these set apart educational areas of the island. This tour will forever be in my list of top sites. The Hidden Craters Hike is fun, educational, and beautiful. I understand so much more about the birds, plants, and geology of Hawaii. The tour guide was enthusiastic and very knowledgeable. We loved roping down into a lava tube. My 12 year old son was able to do the hike just fine. Also, the Ola Brew tour was a nice way to end the day. I liked the ice tea brewed from coffee leaves.
