Lower River Flatwater

High Rocks

High Rocks Park is a public park and swimming hole in Gladstone, Oregon, United States. The park has been known for hosting summer recreation, as well as for diving and swimming accidents. Located right between Interstate 205 and the Willamette River, High Rocks and Cross Parks on the bank of 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 for adrenaline junkies. While the dynamic rocky terrain is ideal for climbing, jumping or sunbathing, it carries 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 the incredible turbulence of the underwater currents. According to officials, High Rocks claims 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.
