Rim Nordic Ski Area is a cross-country ski destination in Southern California's San Bernardino National Forest along Highway 18 near Running Springs and Big Bear Lake. Focused on Nordic skiing rather than downhill runs, it also includes designated snowshoe trails and offers equipment rentals, ski lessons, and a shop with snacks, serving winter day visitors. In warmer months, the area turns to mountain biking and regularly hosts bicycle races sanctioned by USA Cycling. Its role as a year-round outdoor recreation site is reinforced by membership in the Cross Country Ski Areas Association of North America and operation under a special permit from the United States Forest Service.
