What to Expect

Green Lake sits in Mount Rainier's Carbon River district — the park's quietest corner, where old-growth forest swallows the sound of everything except your own breathing. The trail winds through towering Douglas fir and western red cedar, crossing a few modest creeks before delivering you to a glacially-fed lake that earns its name on sunny days, glowing an almost unreal shade of green from suspended glacial flour. The Carbon River area gets drenched with rain — this is temperate rainforest territory — so expect muddy stretches and moss draped over every surface like nature's wallpaper. The lake itself is a peaceful turnaround spot, ringed by forest with Rainier's bulk lurking above the treeline when clouds cooperate. This one rewards hikers who value atmosphere over alpine drama, and anyone tired of the Sunrise and Paradise crowds will find exactly the solitude they're craving.

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.

Pro Tips

Trail Tip

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.

Trail Tip

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.

Trail Tip

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.
