Maunawili Falls Trail

2.8 miles 1,007ft elevation Out/Back Trail Moderate

The Maunawili Falls Trail is a lush jungle hike leading to a scenic waterfall and swimming pool on Oahu’s windward side. This moderate-level hike is popular for its muddy terrain, stream crossings, and adventurous rainforest setting. The trail is currently closed for restoration. The state is working to protect the ecosystem and improve trail conditions. Reopening is expected in 2025. The hike starts in Maunawili, near Maunawili Estates. The first part of the trail passes through a dense rainforest, with ferns, banyan trees, and wild ginger. Expect muddy sections and lots of mosquitos, bug spray is highly recommended. Mid-Hike: The trail requires multiple stream crossings, your feet will get wet. The path is narrow, winding, and sometimes overgrown, adding to the adventure. Some sections have rocky scrambling, requiring good balance. The 20-foot waterfall cascades into a deep swimming pool, making it a great spot to cool off. Cliff jumping is common here, but be cautious as water depth varies. Surrounding cliffs and jungle make this a peaceful, secluded escape. Descent & Return: Follow the same trail back through the rainforest. The total hike takes about 2.5 to 3 hours round trip, depending on stops.

Thoughts from my Hike

This trail was a nice hike through the woods. It is a little muddy in parts and you cross a stream several times. So at least you can wash off any mud you have accumulated on your shoes. I wore removable spikes again, as I personally find they come in handy, especially in the muddy areas or when traversing rocks or roots. The trail has inclines and declines, but nothing major. You will traverse sections of roots and sections with stairs. There were some nice views along the way. The trail ends at a beautiful waterfall with a great swimming hole below. People were jumping from the waterfall into the pool below, and some climbed up higher on the side of the waterfall to jump further. It's not for the faint at heart, and could be dangerous if the water is low in the pool below. The rail is pretty well marked overall.
