The Pu'u O'o Trail is a 3.7 mile long (each way), out and back style hiking trail in the Hilo area on Hawaii's Big Island.

With elevation changes of 398 feet over the course of the trail, it's not an overly difficult hike for most but the length (almost 8 miles round trip) means this isn't for everyone. Of course, you'll always have the option of hiking part of it and turning around at any point.

Getting here is easy as the trailhead is right off of Saddle Road, on the south side, with a small parking area nearby. See our map / directions page for exact location.

The trail heads south and takes you through the 1855 and 1881 lava flows (all hardened lava rock now) as well as through an ohia forest (see Lehua Blossoms And Ohia Trees) and a koa tree forest.

Bird watchers should be on the lookout for i'iwi, 'apapane, 'amakihi, 'elepaio, 'oma'o, 'io, akiapola'au, and nene.

As with any hike, be sure to read Hiking Safety & Essentials before heading out. Since much of this hike is exposed you'll also want to apply plenty of sunscreen to Protect Yourself From Sunburn & Skin Cancer.
