French Pete Trail, Hiking trail in Willamette National Forest, Oregon.

The French Pete Trail runs 9.9 miles (15.9 km) through the valley of French Pete Creek in the Three Sisters Wilderness, Willamette National Forest. From the western trailhead at 1,850 feet (560 m), it climbs about 1,000 feet over 5 miles, and French Pete Creek flows beside it for roughly the first five miles. The old-growth forest holds large Douglas firs and cedars up to 1,000 years old, with sword fern, Oregon grape and twinflower beneath.

In 1938 the Forest Service added French Pete to the Three Sisters Primitive Area, then removed it in 1957 to allow timber sales. A 1968 logging plan drew opposition from the Save French Pete Committee and Senator Bob Packwood. The Endangered Wilderness Act of 1978 protected 45,400 acres as wilderness, effective February 28.

The name French Pete comes from a miner who lived in the valley, and the Save French Pete Committee adopted it during the 1960s and 1970s campaign against logging. Senator Wayne Morse hiked in with activists in 1972, and Senator Bob Packwood urged the Forest Service to drop its logging plan. The valley was one of the first low-elevation old-growth areas designated wilderness, in 1978.

The trail is open for hiking from spring through fall. From the western trailhead at 1,850 feet (560 m), it climbs about 1,000 feet (300 m) over 5 miles (8.0 km) and ends 9.9 miles (15.9 km) from the start. French Pete Creek runs beside the path for roughly the first five miles.

In 1978 French Pete became one of the first low-elevation old-growth valleys in the United States designated as wilderness, under the Endangered Wilderness Act, which protected 45,400 acres effective February 28. The forest's understory of sword fern, Oregon grape and twinflower grows beneath Douglas firs and cedars said to be 1,000 years old.
