Beaver Falls Karst is a unique geologic formation on northern Prince of Wales Island. Surrounded by muskegs and mature forests in the Tongass National Forest, the falls are relatively small but spectacular to see water cascading 40 feet and disappearing into a cave. The cave itself is inaccessible and prone to sudden flooding. You can see features such as sinkholes, deep vertical pits, disappearing streams, and collapsed channels from the safety of an accessible boardwalk trail with interpretive information about the geology of the site. Sandhill Cranes are also known to nest in this area, which is relatively uncommon in Southeast Alaska.

Directions:

From Coffman Cove take Coffman Cove Road/NF-3030 10.5 miles west to NF-30. Turn right on NF-30 and drive 5.1 miles then continue on another 4.4 miles on NF-23 to North Island Road. Turn right on North Island Road/NF-20 and travel 30.9 miles to the trailhead. The drive to the site is approximately 51 miles and a three-hour drive from Coffman Cove.
