Cross Park - High Rocks

Tucked along the banks of the Clackamas River near Gladstone, Oregon, Cross Park and High Rocks offer two distinct swimming experiences within the same stretch of river — and together they make one of the Portland metro area's most beloved unofficial escapes. Whether you're drawn by the thrill of jumping from dramatic basalt ledges or simply want to wade in clear, cool water with the kids, this dual destination delivers the kind of summer afternoon that sticks with you long after the drive home.

The Setting: Basalt, Bridge, and Emerald Water

The Clackamas River runs cold and clear here, pooling into shades of emerald and turquoise that feel almost implausible this close to a major city. Towering basalt rock formations line the banks, sculpted by ancient volcanic flows into angular shelves and deep plunge zones that have made High Rocks a local legend. Just downstream, the energy softens at Cross Park, where the river spreads into gentler, family-friendly wading areas perfect for young swimmers and those who prefer to keep their feet closer to the riverbed. Framing the scene overhead is a historic closed truss bridge — a photogenic relic that adds an unexpected layer of character to the landscape. In summer, the tree canopy filters afternoon light into dappled gold, while spring and fall bring vivid foliage and a quieter, more contemplative atmosphere.

In the Water: Adrenaline and Relaxation

At High Rocks, the deep plunge zones beneath the basalt ledges are the main draw. You'll find locals lined up to leap from the natural rock platforms, dropping into water that runs deep and startlingly cold even on the hottest July days. The clarity of the river means you can watch your own shadow sink beneath you before the cold rush swallows the thought entirely. Downstream at Cross Park, the river calms considerably. Shallow pools and gentle current make it an ideal spot for families with young children, casual floaters, and anyone who wants to soak in the surroundings without the splash. The dual character of these two spots — adrenaline at one end, relaxation at the other — means virtually every kind of visitor finds their rhythm here.
