This is an awesome hike with great views of the windward side and east side of the island. Sitting on 2000ft elevation. The last quarter of the hike is the killer because of the stiff stairs that looks like never ending. A nice view awaits for atop the ridge.
Route from town: Head to Kalanianaole Hwy pass Niu Valley and turn left on Kuliouou Rd to the Trail Head. There is two trails here, one goes to "Kuliouou Valley" and "kuliouou Ridge".
