High Rocks - Clackamas River

A unique rocky bank in the Portland metropolitan area
Strong underwater currents, hidden underwater ledges, crowded on summer weekends



Located right between Interstate 205 and the Willamette River, High Rocks Park and Cross Park on the Clackamas River are not only one of the most popular and heavily visited swimming holes in Portland but also one of the most notorious. Regardless, it is definitely the most visited destination in the quaint and sleepy town of Gladstone.

As the Clackamas begins to converge with the Willamette River, the widening river gets slower and deeper creating a natural swimming pool. The banks of the river are composed of high cliffs which provide for ample jumping opportunities - ideal for adrenaline junkies. While the dynamic rocky terrain is ideal for climbing, jumping or sunbathing, it brings with its own hazards.

The frigid water temperatures alongside the strong currents, hidden underwater ledges, and an undercut bank are a deadly combination. The water simply appears calm on the surface but the tranquil exterior hides incredible turbulence of the underwater currents. According to officials, High Rocks claim from two to four lives annually.

Notwithstanding the danger, High Rocks on the Clackamas River are a perfect getaway to escape the mid-summer heat.



The destination is crowded even though the proximity to the freeway is a deterrent. This is because the High Rocks Park on the Clackamas River boasts of an incredibly unique rocky bank and a breathtakingly picturesque stretch of water.

Furthermore, the rocky and steep outcropping alongside the river provide a perfectly rugged surface for those wishing to indulge in fishing, picnicking or quite simply enjoying the sun. If the ruggedness of the terrain concerns you, it is essential to know that there are now lifeguards employed to prevent accidents from happening, allowing you and your loved ones to enjoy the true beauty of High Rocks.

For purposes to reduce water related accidents at High Rocks, the lifeguard service works from Memorial Day to Labor Day every year.

Cautions: Cliff jumping and slippery rocks are associated with risks, please use caution and make safe decisions.
