Timberline Trail
Mt. HoodBest Aug–Sep
A 41-mile circumnavigation of Mount Hood — one of the great loop hikes in the Pacific Northwest.
About This Trail
The Timberline Trail circumnavigates Mount Hood at roughly timberline elevation, touching every climate zone on the mountain from 3,300-foot old-growth forest near Ramona Falls to 7,300-foot lava barrens at Gnarl Ridge. Completed by the CCC in 1934, the trail threads through wildflower meadows — Paradise Park, Cairn Basin, Elk Cove, Mount Hood Meadows — crosses glacial streams that can turn into torrents on hot afternoons, passes ancient whitebark pine, and skirts the yawning Eliot Glacier.
Most parties take three to four days, camping at established sites like Elk Cove, Cairn Basin, or the shoulder of Lamberson Butte. Most go counterclockwise from Timberline Lodge. The views are constant: every few hundred yards the mountain shows another face, with the Cascade giants — Adams, Rainier, St. Helens, Jefferson, Three Sisters — visible on clear stretches.
Key challenges: multiple unbridged creek crossings (Eliot Creek is the notorious one — time your crossing for early morning when glacial melt is lowest), snow patches that linger into July, and a long, exposed stretch across the east side where weather can deteriorate fast. Prime window is late July through September. Permit system for overnight use — check USFS for current requirements.

Safety & Considerations
Today's Hazard
- Strong sun — sunscreen, hat, and sunglasses recommended; water reflection adds glare near the lake
Persistent Hazards
- Eliot Creek crossing — dangerous in afternoon melt; cross early morning
- Lingering snow through mid-July on the north and east sides
- Exposed ridges with lightning risk in afternoon storms
- Glacial streams rise dramatically on hot days
