Pu'u Pia Trail

Pu'u Pia Trail delivers one of Oahu's most rewarding short hikes, climbing 750 feet through native forest to panoramic views of Honolulu and Diamond Head. This 1.2-mile round trip starts steep and stays that way, making it ideal for hikers wanting a solid workout without an all-day commitment. The trail begins in Kaimuki and winds through native and introduced plants before opening to stunning 360-degree views at the summit. On clear days, you see from Koko Head to the Waianae Mountains. Most hikers reach the top in 30 to 45 minutes. Start before 8 AM to beat crowds and heat. The trail offers minimal shade, so bring water, sunscreen, and a hat. Wear sturdy shoes with good grip since volcanic rock turns slippery after rain. The steepest sections require scrambling over rocky terrain. Street parking along Harding Avenue and nearby residential streets works best. No parking fees apply, but respect posted signs and local residents. The narrow streets fill quickly after sunrise. This trail suits intermediate hikers comfortable with steep, uneven terrain. Families with older children who hike regularly handle it well, but it challenges casual walkers and young kids. The rocky sections demand careful foot placement and basic scrambling skills. The trail stays open year-round with no entrance fees. Dry season months from April through October offer the most reliable weather. Avoid hiking during or immediately after heavy rains when wet volcanic rock becomes dangerously slick. Trade winds provide the best cooling effect during morning hours.
