The Hanauma Bay Rim Hike is a lesser-known, unofficial ridge trail that offers breathtaking panoramic views of Hanauma Bay, Koko Crater, and the Pacific Ocean. This hike takes you above the bay, giving you incredible coastal scenery without the crowds. Important Note: This trail is not officially maintained, and some parts may be steep and eroded. The hike starts near the Hanauma Bay parking lot, just before the entrance gate to the preserve. Walk toward the right side of the parking lot, where a small, unmarked dirt path leads uphill. The trail quickly gains elevation, providing early views of the coastline. Mid-Hike: The path follows the ridgeline along the outer edge of Hanauma Bay. Expect some steep sections with loose gravel, hiking shoes with good grip are recommended. Along the ridge, you’ll see waves crashing into the rocky coastline below and a bird’s-eye view of the reef in Hanauma Bay. The highest point of the hike offers a sweeping view of Hanauma Bay, Koko Head Crater, and even Molokai on a clear day. Some hikers continue toward the back of Koko Crater, but the terrain becomes more rugged. Descent & Return Follow the same path back down, being careful on steep or loose sections. The entire hike takes 1 to 1.5 hours round trip.
