Natural Features and SceneryTall mixed conifers surround the campsites, their canopy creating a secluded forest floor environment. Castle Lake fills a classic glacial cirque just uphill, its granite cliffs polished by ice age glaciers and waters fed by snowmelt and springs. The clarity lets you see the bottom, and the setting changes throughout the day as light shifts across the surrounding granite walls. It's the kind of alpine lake that looks carved rather than filled.

Lodging & AccommodationsNo hotel-style lodging options are available at this campground.
