Judd–Jackass Ginger Pool Professional Guide
Detailed Trail Description from our Guidebook
"This may be the most popular short-hike destination on O’ahu, a place for socializing and swimming as much as communing with nature. Nu’uanu Stream flows along the southwest side of the elongated loop and widens into a pretty ginger-lined pool fed by a 10-foot cascade.
The short loop trail is named for Lawrence Judd, who was a governor of Hawai’i in territorial days, and tradition has it that somebody grazed a donkey in the grass near the pool at one time. It is often crowded, especially on weekends, and parking is sometimes a problem. The best time for a hike is early in the morning on a weekday. You can walk directly to the pool, or hike the loop the long way ’round, rewarding yourself with a swim toward the end."
