Portage Creek Trail
What to Expect
Safety Advisory
This is prime brown bear country with zero cell service and no nearby help — carry bear spray accessible on your chest strap, make noise continuously through the alder section where visibility drops to near zero, and know how to use your deterrent before you need it.
Weather above treeline changes with alarming speed. A sunny morning can become a whiteout with driving rain and near-freezing temps within an hour. Pack rain layers and a warm mid-layer even if the sky looks perfect at the lakeshore.
The alder zone can be disorienting when the trail becomes faint. If you lose the path, head uphill — the route becomes obvious again once you clear the brush line.

Pro Tips
Coordinate your floatplane or water taxi pickup time with plenty of buffer — this trail takes longer than the mileage suggests, and rushing the descent on steep switchbacks is how ankles get wrecked.
Trekking poles are non-negotiable here. The switchback section above the alder zone is loose and steep, and on the descent they'll save your knees a week of complaining.
Once you hit the tundra, keep climbing another ten minutes beyond where most people stop. The higher you go, the more dramatic the lake and glacier views become, and you'll likely have the entire ridgeline to yourself.
