2.5 miles of underground adventure – this is the Ape Cave. The cave is actually a massive lava tube that you can explore on your own. There are lots of fascinating rock formations and petrified lava flows, so take your time to investigate this unique tunnel. In some sections you will have to scramble over large boulders. Bring at least two sources of light and a jacket: it is chilly in there.

The Ape Cave is the third longest lava tube in North America. This is the main entrance for the impressive Ape Cave. The cave consists of a massive lava tube that you can explore on your own. Before you do, though, you have to book an inexpensive ticket for a certain time slot from May through October on https://www.recreation.gov/timed-entry/10086990 – that is to save the cave from the masses and ensure that you can experience this unique formation without being rushed. Bring at least two sources of light (in case one fails), it is pitch black in the 2.5 mile tunnel. Also bring some warm layers as it is just 42 degrees cool even in summer.

The Volcanic Viewpoint Trail leads through a nice forested area. You will gain some, but not too much elevation and pass an old quarry. Once you are almost at Forest Road 8303, the forest opens up a little and offers a stunning view of Mount Saint Helens.
