Mānoa Falls Trail

One of Oʻahu's easiest hikes: 1.6 miles round trip (about an hour) through Mānoa Valley rainforest to a roughly 150-foot waterfall, near Lyon Arboretum above Honolulu. Expect mud and slippery rocks; don't swim in the pool.

• Difficulty: easy, good for beginners.
• Length: 1.6 miles round trip, about 1 hour.
• Trail is rocky and often muddy and slippery; wear sturdy shoes, not slippers.
• Don't swim or wade: the Hawaiʻi Department of Health discourages it because of leptospirosis, and signs warn of landslides and flash floods.
• Parking: a paid private lot at the end of Mānoa Road (fees have been reported between $5 and $7), or free street parking lower in the neighborhood. Confirm current rates on arrival.
