The South Fork Clackamas River is a tributary, roughly 8 miles (13 km) long, of the Clackamas River in the U.S. state of Oregon. Beginning near South Fork Mountain in the western Cascade Range, the river flows generally north through Clackamas County to meet the larger river at Big Cliff. Most of the South Fork's drainage basin lies within the Mount Hood National Forest.
The lower reaches of the river are part of the National Wild and Scenic Rivers System. Recreational opportunities in the basin include hiking, camping, and fishing for trout. A 70-foot (21 m) waterfall prevents salmon and other migratory fish from swimming upriver beyond the first 0.4 miles (0.6 km).[5]
