Headed up the Pu`u Pia trail with Kai to the Waiakeakua Falls. At a saddle at the back of the Pu`u Pia trail we headed down a steep and slippery side trail that leads to the Waiakeakua stream.
From the stream, there is a nice and relatively easy trail that winds with the stream. Along the stream are some decent sized pools and small waterfalls.
The trail crosses some old Board of Water Supply pipes and tunnels, including a man-made falls.
Though pretty flat, the trail is quite muddy and moss covers everything else.
After a couple of miles the lower falls of Waiakeakua appear.
After climbing around a small pool at the bottom a bigger pool and waterfall await.
We decided against trying to scamper up the side ridge trail to the Pu`u Pia trail and instead opted for the Seven Bidges of Manoa trail that exits on Waaloa Way (near the Manoa Falls parking lot). The area used to be populated and there are some reminders of what the area used to be.
After crossing a few bridges we made our way back out of the jungle and back to my car, parked at the Pu`u Pia/Kolowalu trail-head.
