I read good things about this hike so I decided to check it out when I was in Honolulu. One of the most amazing ascents I have ever done. Cool jungle scenery, technically challenging without being too unsafe, you get to hike up waterfalls, you get great views of the island, and I only saw two other hikers. The descent was rough though. I expected it was going to be really muddy, so I brought an old pair of tennis shoes I could throw away when I was done with the hike. I didn't expect it to be super steep, and so the lack of traction provided by the old shoes ended up being problematic. Lots of slipping and falling, but totally worth it.
