Maunawili Falls

Maunawili Falls rewards hikers with a 20-foot waterfall and swimming hole at the end of a muddy 3-mile round-trip trail through Oahu's rainforest. The moderate hike takes most people 2-3 hours total, crossing several stream beds and climbing over rocks and roots along the way. The trail starts steep and stays challenging throughout, with slippery conditions year-round due to frequent rain. Red dirt will stain your clothes and shoes permanently. Sturdy hiking boots with good grip are essential - tennis shoes won't cut it here. Bring plenty of water, snacks, and a waterproof bag for your phone. The payoff comes when you reach the falls. The pool runs deep enough for swimming and cliff jumping from lower rocks. Water stays cool and refreshing even on hot days. Local families often picnic here on weekends. Park along Maunawili Road near the residential area - look for the small trail marker past Auloa Road. No parking fees apply, but spaces fill up by mid-morning on weekends and holidays. Start early, ideally by 7 AM, to avoid crowds and afternoon heat. This trail suits intermediate hikers comfortable with uneven, muddy terrain. Families with young children or anyone with mobility issues should choose easier options. The trail becomes extra slippery during heavy rains - check weather conditions before heading out. No entrance fees required. Bring reef-safe sunscreen, insect repellent, and a change of clothes for after your swim. The return hike feels longer uphill.
