On northern Prince of Wales Island, Beaver Falls cascades about 40 feet before disappearing into an adjacent karst cave. An accessible 1.5-mile round-trip boardwalk trail passes sinkholes, disappearing streams, and interpretive signs about the limestone karst.

At 40 ft, it stands above roughly 33% of the 775 documented falls in this guide.

Beaver Falls sits on unknown. You'll find it in Prince of Wales-Hyder, Alaska. It is protected within Tongass National Forest (USFS).

This is a short hike waterfall: reached by a short trail, generally under about a mile each way. A short walk gets you to the viewpoint, so it works for most casual visitors and families. The walk to the main viewpoint runs about 1.5 miles round trip. Base a visit out of Whale Pass, the closest town.

When to go: Summer (Jun-Sep). Expect the strongest flow in spring and after big storms, with a quieter trickle by late summer; confirm current conditions with the land manager before committing to the drive.
