Wiliwilinui Ridge Trail

The Wiliwilinui Access Road and Ridge Trail starts as a rugged dirt road through Formosa koa and guava forest, then climbs straight up the ridge past a Hawaiian Electric tower to a small knob on the Koʻolau summit with a view of the windward coast. A staircase of recycled plastic planks covers the first steep part of the final climb, and from the summit you can also see the leeward coast and Waimānalo. Tall Cook pines planted by Territorial Forestry stand along the ridge top. Hikers reach State land through the Wiliwilinui Community Association's property in Waiʻalae Iki: from Kalanianaʻole Highway, turn up Laukahi Street, check in with the security guard, continue to the end of Laukahi, turn left on Okoʻa, and park before the cable gate. Stay on the designated access and follow the association's rules. The access road ends at a turnaround with a bench, a bike rack and a boot cleaning station, and mountain bikes may use the road but not the trail. Hunting dogs may be off leash during a hunt, cliffs are a listed hazard, and dogs must be leashed; alcohol, open fires and commercial use are not allowed. Hawaiian Electric built the dirt road to reach its power lines, and Nā Ala Hele and trail advocates later negotiated legal access through the subdivision. DLNR reopened all of Oʻahu's forestry and wildlife lands in late September, and it asks hikers to take care, since hazards it has not yet found or fixed may remain.
