Pihea Trail is located at the end of the road at the top of Waimea Canyon past Kokee State Park and by the Pu'u O Kila Lookout. There is a trail sign along with a well faded sign saying - "Mt. Waialeale Wettest spot on earth"
The Pihea Trail is among the premier hiking paths in the Kokee/Waimea Canyon area. The trail traverses the narrow ridge in the Na Pali Kona Forest Reserve between the Kalalau Valley and the Alakai Swamp. The views extend 4,000 feet down the mossy, fluted cliffs of the Kalalau
Valley, which drops sharply into the ocean. The views inland extend over layers of folded forested canyons and ridges to Mount Waialeale, the wettest spot on earth with an average of 450 inches of annual rainfall.
Alakai Swamp is an incredible, atmospheric area like nowhere else. Swamp weather can cause no views at all and is typical weather.
The trail begins as an old road (An attempt to build a road to Haena).
The trail is quite rutted and it's easy to see why the attempt failed. There are numorous lookout areas to the Kalalau Valley. Along with the elevation changes up and down through a fern lined path, there are many wet muddy areas. Some spots have a wooden walkway in areas that are wet all the time.
