Judd Trail in Honolulu, HI

Judd Trail is a short and challenging trail just 10 minutes outside Honolulu. Hike under cover of ironwood, pine, eucalyptus, and bamboo on your way to the Jackass Ginger Pool.

Jackass Ginger Pool is an 8-foot-deep pool featuring a 10-foot waterfall. This popular swimming spot was named after someone who tied up their donkey by the pool in a ginger patch.

Wild pig hunting is permitted in this area from sunrise to sunset on Wednesdays and Sundays. The trail is still open for hiking, but hikers should be aware of the hunting and take extra care to read and heed all posted signage.


You shouldn’t have trouble seeing the trailhead off 4022 Nu’uanu Pali Drive. Look for a clearing in the Ironwood forest along the road.

Trekking poles aren’t necessary for most hikers, but you may want to bring them if you have balance issues due to mud and other tripping hazards.
