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.

Before you go

Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check Tongass National Forest (USFS) for closures and current conditions, and confirm land status before setting out.

Frequently Asked Questions

Beaver Falls drops about 40 feet. That makes it the 494th-tallest documented waterfall in this inventory, taller than roughly 31% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.

The Beaver Falls Karst Trail reaches it about 1.5 miles (out-and-back), rated easy. The nearest town is Whale Pass. That describes the route as documented, not conditions on the day — check with Tongass National Forest (USFS) for closures and current conditions.

Summer (Jun-Sep). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
