Timberline Trail is a hiking trail around Mount Hood in the U.S. state of Oregon. It is in mostly wilderness but also goes near Timberline Lodge, Cloud Cap Inn (the oldest building on Mt. Hood), and Mount Hood Meadows ski area.
The Timberline Trail was constructed in the 1930s by the Civilian Conservation Corps, the majority of their work taking place in the summer of 1934 at a cost of $10,000. Sections of the trail have changed due to damage caused by landslides and washouts since then. In September 1938 a group of hikers completed the entire trail (36 miles at the time) in 47 hours, making local news and increasing awareness of the trail.
The trail, Forest Service trail #600, shares eleven miles (18 km) with the Pacific Crest Trail and alternates above and below the timberline. The trail is rerouted periodically due to washouts and to avoid sensitive high altitude and alpine meadows. It has a handful of informal campsites for backpackers, although camping is permitted anywhere outside the meadows and at least 200 feet (61 m) from water bodies. There are several hazardous stream crossings, especially on the west side and at landslide-prone Eliot Branch near Cloud Cap which closed the trail there in 2007. The trail has several significant vertical ascents and descents totaling 9,000 feet (2,700 m), mostly at canyon crossings. The trail is accessible from Timberline Lodge, which has Forest Service permitted parking (which you can purchase at Timberline Lodge) for backpackers, and numerous connecting trails.
