Nuʻuanu Pali is a section of the windward cliff of the Koʻolau mountain located at the head of Nuʻuanu Valley on the island of Oʻahu. It has a panoramic view of the windward coast of Oʻahu. The Pali Highway connecting Kailua/Kāneʻohe with downtown Honolulu runs through the Nuʻuanu Pali Tunnels bored into the cliffside.
The area is also the location of the Nuʻuanu Freshwater Fish Refuge and the Nuʻuanu Reservoir in the jurisdiction of the Hawaiʻi Department of Land and Natural Resources.
Non-residents have to pay for parking ($3); taking the bus might be best.
