This boardwalk trail is located through a 1900 year old lava flow. The scenic loop takes you to many examples of the vertical molds left behind when hot lava flowed through a living forest and surrounded the base of the trees. After the trees burned up, there was a hole left where they had been, and those holes, or molds, are visible to us today.

There are even some horizontal molds where the lave flowed over fallen trees, and when they burned up, a holes were left in there place. Some of these holes are large enough for visitors to crawl through.

As you can imagine, this area is extremely fragile, so please walk only where indicated.
