About This Route
Index to Big Creek on the Skykomish River, adjacent to PCT Section 28 (Stevens Pass area), serves Class III rafting in Washington's Alpine Lakes Wilderness gateway. Launch at Index (Mt. Si NRCA), paddle 12 miles through evergreen forests with rapids like Boulder Drop and Devil's Club. PCT hikers cross nearby; combine for shuttle via US 2. Peak flows May-July (1500 cfs); 4-hour runs. USFS Alpine Lakes permits for overnight camps.
Safety Considerations
Wood jams and strainers from log runs mimic PCT crossing dangers; scout bends. Steep banks erode, risking slides. Cold glacial water (35-50°F) heightens hypothermia. Thunderstorms build cumulonimbus; monitor NWS Seattle. Avoid solo per American Canoe Association.
