About
The Southwest Walk-in Campground is located on the east side of the Kohm Yah-mah-nee Visitor Center parking area. When snow is present, approximately November to May, overnight stays are only allowed in self-contained vehicles in the parking lot (walk-in tent sites are closed in winter). Regulations change and the walk-in tent sites are open when the snow melts, approximately June to October.
Fees
Self-Contained Vehicle Site: $10. Camping in a self-contained vehicle in the adjacent parking area only. Please park between islands to allow for plowing activities.
