Waihe’e Ridge Hike
About five miles IIRC, 1,500 feet in elevation, out-and-back, all-up then all-down. It’s about as typical a Hawaii hike as there is, where “typical” means “average”. Some nice views, distant waterfalls, a lot of green stuff, but nothing that makes you gouge your eyes out when you get to the bottom in order to ensure that no future images will crowd out the unremitting wonder of the sights you just beheld.
