Calling the hike "extremely dangerous" is an exaggeration. I've never had a single person get seriously injured, which is a testament to the safety. The ‘A‘ā lava is nowhere near as unstable and precarious as the reviewer makes it seem. The spots on the hike where there is elevation gain are especially solid and stable, and for the most part, you're not close enough to the edge for it to be dangerous. This group ended the hike after 50 feet based solely on the sight of the first hill, so the reviewer is not qualified to analyze the stability of the hills. The oldest child was the only one who climbed up the first hill, but that area was very stable and the child was never in any danger. Over half of the hike is very flat and easy. It just so happens that the harder parts are in the beginning. I've had some younger kids do the hike and they were fine, although the parents were more hands-on. One of my biggest demographics is parents in their 40s & 50s with or without their teenage children, so I do not agree with the "20/30/40" recommendation the reviewer makes. The lower age cutoff is probably about 8 years old, although that will depend on the parent and child. There really isn't an upper age cutoff as long as you don't have a disability. Because this group ended the hike so quickly, I didn't get a chance to give them a "real tour", to discuss the history of the area, for example, which I know a fair amount about. Sometimes I talk more, sometimes I talk less. It just depends on what I feel the group wants.
