The Judd Memorial Trail and Jackass Ginger Pool hike is a surprisingly good and easy hike in the Honolulu of O'ahu.

The trail takes you through a small bamboo forest, along a flowing river, a natural swimming hole, and even lets you see waterfalls in the first few seconds of the hike. Fans of the TV show Lost may recognize parts of this trail as it was in many episodes over several seasons.

To get started, head to our map pin point which will mark the trail head. The only option for parking is along the street here and, as always, never leave anything in your car.

Head onto the hiking trail and you'll hear the sound of water right away. Follow the path down and in just a few feet you'll see a running stream with a small waterfall off to your left. This is one of the easiest places to see a waterfall on Oahu, even if it's not as large as others.

If you plan to hike the full trail, which is a loop of around 0.75 miles, then you'll need to cross the stream. Some cross on the rocks (when the river is lower) and stay dry, but keep in mind that they can be really, really slippery. And others just walk through the water which is mostly shallow with a few spots that might dip you in as foot or more.

You should be cautious of the potential of a Flash Flood here and if the stream is anything but calm then don't risk it. While this can be a child friendly hiking trail, the river crossing is certainly the one area you'll need to be extra cautious with kids.

Once you cross you'll just follow the trail which is relatively flat with some very minor elevation changes. There are rocks, some muddy areas, and lots of slippery tree roots all over the path but it's very easy overall and the entire trail loop from start to finish will only be about 1 mile.

Along the route of the Nuuanu Stream, as you approach some houses in the distance, you'll come across the Jackass Ginger Pool portion of the hike. This is a natural swimming hole complete with some rock waterslides people like to play on. We're not here tell you to jump in or not, but if you do swim here (or in any freshwater anywhere in the islands) be aware of the risk of Leptospirosis.

Note that this trail will also connect to the Nu'uanu Trail which will be far more difficult so novice hikers should stick to the Judd Trail. If you do hike further the Nu'uanu Trail will eventually then connect to the Judd Memorial Trail and Jackass Ginger Pool

As always, make sure you have good footwear and bring water. Pack out anything you brought on the hike and never drink the water in streams or waterfalls due to the risk of Leptospirosis. Now is also a great time to go and read up on Hiking Safety & Essentials.
