Mānoa Falls is a rainforest waterfall located in Manoa Valley on the island of Oʻahu, Hawaii and is a popular short-hike destination near Honolulu. The waterfall is reached via the Manoa Falls Trail which passes through dense tropical vegetation and a wet valley environment.

The trail is a single-track rainforest path that can become muddy and slippery after rain; it ends near the base of the falls where a pool collects runoff from the cascade. Visitors come for the rainforest walk, native plants and the waterfall view; swimming is commonly discouraged for safety and health reasons.

The falls and valley have long been part of local land use and later recreational use; the trail has been maintained for public access to the scenic site. Management focuses on visitor safety and preservation of the valley’s ecological character.

Mānoa Falls is located in Manoa Valley, just inland from Honolulu on the island of Oʻahu, within easy driving distance from the city and accessible by local roads and parking areas.

  • Trail conditions: Trail to the falls is often muddy and slippery after rain; wear closed-toe shoes and be prepared for muddy conditions and occasional trail closures due to weather or safety.

How to Get to Mānoa Falls #

The trailhead is in Manoa Valley a short drive (5-10 minutes) from the University of Hawaiʻi at Mānoa. From downtown Honolulu follow Pali Highway (H-61) east to Wālia Lane, turn onto Manoa Road and follow it uphill to the small parking areas near the trailhead. There is limited street parking; many visitors arrive by rideshare or bus (TheBus route 5 and 14 stop in Manoa Valley - walk 10-20 minutes from the bus stops to the trailhead).

Tips for Visiting Mānoa Falls #

  • Go early (before 9am) to avoid crowds and enjoy cooler light in the valley.
  • Check trail conditions - the trail is often closed after heavy rain due to rockfalls and muddy, slippery steps.
  • Park on Manoa Road and walk; the neighborhood enforces residential parking - avoid parking on private driveways.
  • Bring insect repellent and a light rain jacket; the valley gets sudden showers and there can be leeches after rain.
