Primarily a switchback trail that starts from Judd Trail and takes you up to Pauoa ridge. Once the ridge is gained, make a sharp left and head towards the Koolau along the ridge. You will pass a bench with great views of the valley and the adjacent Tantalus ridge and Pu'u Ohia. Continue along the ridge until you hit the Pauoa Flats Trail. From here, you can turn around and go back to where you started or explore further. Taking the left turn and passing Aihualama Trail junction will take you to a nice lookout point of Nuuanu Valley and reservoir. Taaking the right will take you to Kalawahine or Manoa Cliffs/ Puu Ohia and beyond.

Off of Pali Hwy, Judd Trail to Nu'uanu Trail was a great hike, but was super muddy with lots of tree roots on Sep 25th. Rock crossing at creek slippery. Great views. 10 year old handled it just fine. Would do it again when dry.

Crossing a lot of river rocks. Need good grip shoes. Follow the river.

Couldn't find the trail the directions to the spot led us to the middle of no where waste of time. Maybe would have been better if we could have found the actual hiking trail

We started from Judd Trail, hop over some rocks to cross over the river, and made our way towards Nuuanu Trail, which branches off from Judd ( a loop trail to Jackass ginger) Nuuanu Trail has a few switchbacks and most f the way is clear except for a few eroded sections and blowdowns but nothing dangerous. Got to the ridge top in 45 minutes and headed right along the ridge instead of the left towards Koolau range. The ridge towards makai was quite clear and not too difficult to walk on. Found some huge mango trees and also came aross a family of pigs and piglets! We hiked all the way until we came to the top above a house. This is where we stop. There is also a junction ( heavily ribboned) that takes you down to the valley and Pauao stream ( which is usually dry). Lookout for old poles and pipe system of yesteryears. Further up along the Pauaoa stream are two waterfalls so wait for the right time. You canlso access these waterfalls from Kalawahine trail ( shorter way too). Plan ahead with a topo and bring enough water as the ridge top can be very hot and thevalley very humid during the summer months.
