Overview: The Maunawilli Falls Trail is a great hike in Kailua along the river that eventually stops at a beautiful waterfall with a great swimming hole below. Many people like to jump from the waterfall into the pool below, and some with a bit more courage even climb higher to the side of the waterfall to jump further (try at your own risk).
The trail is often muddy, especially after rains, and you will cross the river several times along the trail. About half way through the hike you will break out of the trees for some nice views of the surrounding mountains and views towards Kailua in the distance.
Tips: Park far from the trailhead–there are strict parking regulations and you don’t want a ticket.
This trail follows creek and is usually very wet and muddy. Wear appropriate shoes (sandals are very hard to walk in once they get muddy).
Almost all of this hike is covered, but mosquitos and other bugs can be a pain. Wear bug spray or keep a good friend close behind you to swat away the pests or you will end up with quarter-size bite marks.
Parking is strictly enforced near the trailhead, so it is best to park on the other side of the bridge in the more residential area. Follow the signs for the Maunamili Trail.
Maunawili Falls Trail
Follow the sign for the Maunawili Falls Trail. You will cross the river a couple of times, and there is a good chance that some of the trail will be very muddy and slippery, so watch you step.
After the uphill climb you will have nice unrestricted views of Kailua towards the ocean. After this you will hike back down hill, and the trail to the waterfall is nearby.
