About Green Lake
Green Lake sits in a part of RMNP where terrain context matters: Glacier Gorge / Bear Lake Corridor, 11,542 feet, east of the Continental Divide. This guide treats it as a hard lake.
Glacier Gorge is one of the park's classic glacial valleys, with lakes stacked from lower forest to upper alpine basin. It is in upper Glacier Gorge. The approach from Glacier Gorge TH is 5.8 miles one-way and belongs in the hard tier for this guide.
NPS trail tables show Glacier Gorge as the starting point for Alberta Falls, Mills Lake, Black Lake, The Loch, Sky Pond, and Andrews Glacier, so lakes here often sit on routes that continue well beyond a single shoreline.
