About This Route
PCT through Three Sisters Wilderness (Oregon miles 1950-2020) spans 70 miles from Santiam Pass to Shelter Cove past North Sister, Middle Sister, and South Sister volcanoes. Lava fields, Obsidian Falls, and Chambers Lake define this accessible backpacking gem. No permits needed, but Central Cascades fire closures common; check fs.usda.gov. Ideal 4-7 day trips with resupply options.
Safety Considerations
Volcanic streams like Separation Creek swell rapidly; cross early morning, pole-assisted, avoid log jams/strainers per NPS. Lava rock ankle-breakers; high-top boots like Salomon Quest 4D. Heat on exposed South Sister approach; 4 liters water capacity. Bears scarce but mice plague; hang food 12 feet. Lightning over summits; below treeline by noon. Wildfire smoke; monitor AirNow.gov. Stay alert near Highway 242; group travel advised.
Essential Gear
SPOT X for two-way comms; Sawyer Squeeze filter; REI Co-op Kingdom 4 tent. Leki Micro Vario poles.
