Manoa Falls is Honolulu's most accessible rainforest hike: a short, well-trodden trail in the green valley above the city that ends at a waterfall of roughly 150 feet. The path climbs gently through bamboo, hala trees and giant ferns, past streams and filtered light that feels a world away from Waikiki. It is easy enough for most fitness levels and children who like to walk, though the trail is often wet and muddy. Go early, bring good shoes and a rain jacket, and you will find one of the most atmospheric short walks on the island.
The trail begins at the top of Manoa Valley, which gets more rain than the coast and shows it in the vegetation. A paved road leads to a small parking lot and the start of the path, and the trail then runs about a mile and a half round trip depending on how you count. You pass bamboo groves, towering trees and tangles of vines, with the sound of water growing as you near the falls.
The Manoa Falls cascade falls down a cliff into a pool; swimming is not allowed, and rockfall can occur, so stay on the designated viewing area.\n\nPlan for mud and humidity. Even in the dry season the path can be slick, so closed-toe shoes with grip are worth bringing. The walk typically takes an hour or two depending on pace and photo stops.
Bring insect repellent, water and a poncho. Leptospirosis can be present in freshwater, so keep cuts covered and do not wade. Parking has a modest fee and fills early on weekends. If you do not have a car, many shuttle and guided options pick up from Waikiki and sometimes combine the hike with a beach or lookout stop.\n\nMake a half day of it. After the hike, visit the nearby Lyon Arboretum, wander through the University of Hawaii campus, or eat at one of the casual restaurants in Manoa Marketplace.
Because the weather in the valley can differ from Waikiki, check the forecast but do not cancel automatically: a morning drizzle often clears. For photography, early morning light makes the green glow, and midweek mornings are quieter than weekends. Respect the forest by staying on the trail and packing out everything you bring.
