This was our favorite activity when my wife and I honeymooned in Hawaii. I surprised her by signing up for a waterfall hike, and we were not disappointed. They drove us to the starting point, and the two guides led the way from there. We hiked a couple miles to the waterfall, had a nice lunch there that the guides carried in their packs, and then hiked back to where the vehicles dropped us off. It’s best if you’re at least somewhat in shape.
