Lulumahu Falls is a 2–2.5 mile round-trip hike that typically takes 1.5–2 hours. The trail is moderate, often muddy with stream crossings, and winds through lush jungle to one of Oʻahu’s scenic waterfalls, which flows year-round thanks to Nuʻuanu Stream (stronger after rain, lighter during dry periods). Follow the ribbons and have a great hike 💯🤙🏽❤️ To legally complete the hike, you must have a watershed permit, which costs only $2.50 and can be purchased online in advance through the official Hawaiʻi DLNR website. #lulumahufalls #hawaiihikes #waterfallhike #waterfall #hawaiiwaterfalls
