Franklin Falls swimming pool

Waterfall · Washington

About this swimming hole

A classic Snoqualmie Pass waterfall with a swimming pool at its base, reached by an easy two-mile round-trip hike through old growth. It's packed on summer weekends, but the cold, misty plunge at the falls is worth arriving early for.
