About This Route
The Three Sisters Wilderness in Oregon's Cascades hosts PCT miles 2,100-2,200, with camps at Lowa Lake, Denali Camp, and near South Sister summit trail. Lava fields, obsidian flows, and glacier views define this volcanic wonderland. Secure a free self-issue permit at trailheads; fires often banned, check Deschutes National Forest alerts. Practice Leave No Trace: pack out all waste, camp on established sites.
Safety Considerations
Heavy mosquito populations June-August require full coverage. Sudden whiteouts from Pacific storms drop visibility; carry navigation tools. Pumice fields cause ankle twists; use sturdy boots. Water reliable at lakes but filter always. Avoid hitching solo from road crossings like Highway 242; keep valuables secure. Limit to small groups as sites fit 4-6 tents. Messy campsites signal lost hikers: alert Oregon Cascades rangers.
Essential Gear
REI Kingdom 4 tent for wind, bug-proof bivy, water treatment (Aquamira drops), and emergency bivy (SOL). Pack puffy jacket (Patagonia Nano Puff), headlamp with red light, and multi-tool.
