Just over 43 miles from Portland up Oregon Highway 224, the Clackamas River has carved and squeezed its way through an ancient basalt lava flow. The Narrows is a unique spot where the river becomes pinched by this now eroding igneous rock, and the current subsequently slows as the riverbed deepens. The Narrows is an amazing retreat on a hot mid-summer day.
Swimming holes and cliff jumping can be extremely dangerous and unpredictable outdoor activities that pose significant risks regarding personal safety. Changing water levels, unseen rocks, and river bottoms that have shifted with currents and seasonal weather can turn a well-known jumping area into a serious hazard. Prior to engaging in these activities, extensively scout the current conditions, and understand the risks involved with serious injury and the logistical challenges of evacuation from the water so you can make safe decisions.
