“Underground tunnel through old lava tubes.
— Ben Wagner
Looking for a different type of journey? This trail that includes navigating an underground tunnel through old lava tubes is sure to please! Just make sure to bring the headlamp!
You'll NEED a strong flashlight, headlamp, or lantern. The ranger station at the trailhead will rent a lantern for a nominal fee. You'll also need warm layers. The tunnel stays 42 degrees year round as it is insulated from the weather outside.
A short distance from the parking lot brings you to the entrance to the tunnel. The tunnel itself is straight-forward, and there is no way to get lost, although there are two sections. The lower tunnel is fairly easy, with no obstacles. It is very good for children.
The upper tunnel requires some light scrambling: As you navigate the upper tunnel, expect to climb over rocks that have fallen into the pathway. Once you reach the end of the upper tunnel, you'll see a ladder leading back to the surface.
Following the path will take you back to the parking lot through a forested trail. The darkness of the cave, in contrast to the vitality of the forest excites the senses, and will make any visitor appreciate the various flora and fauna along the path.
