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 Washington State Parks (Olallie State Park) for closures and current conditions, and confirm land status before setting out.

Frequently Asked Questions
Twin Falls drops about 135 feet. That makes it the 135th-tallest documented waterfall in this inventory, taller than roughly 80% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Twin Falls Trail (Olallie State Park) reaches it about 3 miles (out-and-back) with roughly 500 feet of elevation gain, rated moderate. The nearest town is North Bend. That describes the route as documented, not conditions on the day — check with Washington State Parks (Olallie State Park) for closures and current conditions.
Year-round; biggest flow late winter and spring. Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
