About this swimming hole
High Rocks is the Clackamas River's legendary swim spot, where basalt cliffs from 10 to 30-plus feet ring deep, clear pools. Generations of Portlanders have jumped, swum, and sunned here on hot summer days. The rocky point above the river is the social center of the upper Clackamas in July and August.
