Kaimu Beach Trail
Cool 1/4 mile hike to the sea over the 1990 flow
Directions Maps, and Info
Overview
The Kaimū Beach Trail leads to one of the newest black sand beaches on the Big Island, formed by the 1990 lava flow that buried the original Kaimū Bay and Kalapana village. Today, a short hike across hardened lava fields takes visitors to a striking, rugged coastline where new land continues to form.
Unlike older black sand beaches, Kaimū’s shoreline is made up of coarse, jet-black lava fragments, with powerful waves crashing against the fresh cliffs. While swimming is not safe due to strong currents, this hike offers an incredible look at Hawai‘i’s constantly changing volcanic landscape.
