Manoa Falls

Manoa Falls is a spectacular 150-foot waterfall located in the Manoa Valley on the island of Oahu, Hawaii. This natural attraction is part of the greater Honolulu area and is a popular destination for hikers and nature lovers. Surrounded by a lush rainforest, the falls and the trail leading up to it offer a refreshing escape from the city’s hustle and bustle and provide a glimpse into Hawaii’s diverse flora and fauna.

The Trail to Manoa Falls

Hiking Adventure

The trail to Manoa Falls is approximately 1.6 miles round trip and is considered a relatively easy hike, making it accessible for most people. The path is well-maintained, although it can be muddy and slippery due to frequent rain in the valley, so proper footwear is recommended.

Rainforest Ecosystem

As hikers make their way to the falls, they pass through a dense rainforest canopy, home to various native and introduced plant species. Towering banyan trees, bamboo groves, and the fragrant scent of ginger blossoms create a verdant, tropical atmosphere that enchants visitors.

Filming Location

The captivating scenery of Manoa Falls and its trail have been featured in several movies and television shows, most notably in the TV series “Lost” and the movie “Jurassic Park,” showcasing the valley’s cinematic qualities.

The Waterfall

Upon reaching the end of the trail, visitors are greeted by the sight of Manoa Falls, a narrow cascade that drops 150 feet into a small, rocky pool below. The water flow varies depending on recent rainfall but is generally consistent throughout the year.

Safety Precautions

Swimming at the base of the falls is not recommended due to the risk of falling rocks and potential contamination from Leptospirosis, a bacterial infection that can be present in freshwater streams and ponds.

Ecological Importance

Watershed Protection

The Manoa Valley serves as an essential watershed for Honolulu. The lush vegetation and natural landscapes play a critical role in capturing and filtering rainwater, replenishing groundwater sources, and preventing erosion.


The area around Manoa Falls supports a diverse range of wildlife, including native birds like the apapane and amakihi, which can sometimes be seen flitting among the treetops. Efforts to control invasive species and preserve native plants are ongoing to maintain this biodiversity.
