Sight · Haleakalā National Park
A natural bridge between Koʻolau Gap and the crater floor
Overview
Rainbow Bridge is a natural land bridge: a narrow rocky ridge on Halemauʻu Trail above the descent into Haleakalā’s crater. The view opens toward Koʻolau Gap on one side and the crater floor on the other. It’s worth a stop if you’re already hiking Halemauʻu, not a drive-up overlook. The access is rocky, narrow and steep, and the return climbs; allow more time for the uphill leg. Published directions disagree on the distance to the bridge, so check a current trail map instead of planning around a precise out-and-back mileage.

Guide
Koʻolau Gap lies to the left of the trail, with the crater floor to the right. Take a moment to look both ways. For a photo, leave some of the narrow path and ridge in the foreground so the land bridge reads clearly. Clouds can hide the crater, so the full panorama depends on visibility.
The bridge is natural, but the Civilian Conservation Corps improved it. The Corps ran work camps at Haleakalā from 1934 to 1941 and built Halemauʻu Trail; mules helped haul lumber and gravel into the crater. That history gives this short ridge stop a connection to the much longer trail network.
High-altitude weather changes quickly: cold, wind, rain and strong sun are all possible. Bring layers, water and sun protection, stay on the marked trail, and leave pets behind. There is no food, supplies or gas in the park.
