San Bernardino Mountain Town
About Twin Peaks, CA
Welcome to Twin Peaks, an unincorporated San Bernardino County community in the heart of the San Bernardino Mountains near Lake Arrowhead.
Twin Peaks is an unincorporated community in San Bernardino County, California, located in the heart of the San Bernardino Mountains. The community sits within the broader Lake Arrowhead census-designated place and along California State Route 189, the road that runs through the area before reaching Lake Arrowhead. With a population of roughly 2,250, Twin Peaks is one of several mountain communities, along with Crestline, Lake Arrowhead, and Running Springs, that occupy the forested slopes east of the San Bernardino Valley. The community's identity is tied to the San Bernardino National Forest and the recreational landscape that surrounds it. The mountains offer a four-season climate, with snow in winter and cooler summers than the valleys below, and Twin Peaks has long served as a residential and vacation destination for the greater Los Angeles and Inland Empire regions. A mix of full-time residents and seasonal homeowners shapes the community's character. State Route 189 provides the community's main connection through the mountains, linking Twin Peaks to Lake Arrowhead and the other mountain towns, while the larger mountain highways descend to the San Bernardino Valley and the cities below. This geography gives residents access to both the quiet of the forest and the employment and services of the lowlands. Students in the area are served by the Rim of the World Unified School District, which covers the mountain communities. Today Twin Peaks functions as a small, unincorporated mountain community defined by its forest setting, its proximity to Lake Arrowhead, and the outdoor recreation that draws people to the San Bernardino Mountains throughout the year.
