Green Lake
What to Expect
Safety Advisory
Creek crossings can become hazardous during snowmelt or after heavy rain — water levels in the Carbon River drainage rise fast and footbridges in this area have a history of washing out, so check ranger station conditions before heading in.
The Carbon River valley is prime black bear habitat — make noise on the trail, carry your food in a bear canister if overnighting nearby, and know how to handle an encounter.
Trail Details
- 1
The Carbon River Road has been closed to vehicles for years, which means you'll need to bike or hike the road before even reaching the trailhead — factor in the extra mileage and plan accordingly, or bring a mountain bike to cover the road section faster.
- 2
This corner of Rainier gets some of the heaviest rainfall in the park, so gaiters and waterproof boots aren't optional — they're the difference between a good day and a miserable slog through ankle-deep mud.
- 3
Visit in late June or July when the wildflowers pop along the lakeshore and the glacial melt turns the water that signature green — by late summer the color fades and the lake loses some of its magic.
