Rim of the World Scenic Byway is a National Forest Scenic Byway that traverses the San Bernardino Mountains in Southern California, linking lowland urban corridors to highland forests, alpine meadows, and reservoir landscapes. The route connects communities, recreational sites, and transportation corridors while offering views across the Mojave Desert, Inland Empire, and Sierra Nevada foothills. It is managed within the jurisdictions of federal, state, and local agencies and is a focal corridor for tourism, conservation, and regional mobility.

Route description

The byway begins near San Bernardino, California and follows a series of state and county roads climbing into the San Bernardino Mountains, passing through communities such as Rialto, California, Fontana, California, Colton, California, Loma Linda, California, and Highland, California. It ascends via routes that intersect with Interstate 10, California State Route 18, California State Route 38, and county-maintained roads near Running Springs, California and Big Bear Lake, California. Along the corridor the road skirts prominent features including Lake Arrowhead, California, Big Bear Valley, Snow Summit, Mount San Gorgonio, and the San Andreas Fault. The byway threads through federally managed lands such as San Bernardino National Forest and passes within sight of Angeles National Forest boundary peaks, providing direct access to alpine trailheads tied to the Pacific Crest Trail, San Bernardino Peak, and the Santiago Peak viewing network. Connections at lower elevations link to transit hubs like San Bernardino Transit Center and freight corridors served by BNSF Railway and Union Pacific Railroad freight lines.

History

The corridor follows historic wagon and logging roads established during 19th-century expansion by settlements tied to Gold Rush, Santa Fe Railway expansion, and the development of Southern California water infrastructure connected to entities such as the Los Angeles Department of Water and Power and early irrigation schemes tied to Owens Valley water disputes. In the 1880s and 1890s, tourism growth promoted rail and stagecoach links from Los Angeles, California into the mountains, with hotels and resorts near Big Bear Lake and Lake Arrowhead. During the 20th century, automobile tourism boomed alongside the construction of Interstate 10 and California State Route 38, while federal conservation initiatives under the United States Forest Service shaped land use. The byway received formal designation as a National Forest Scenic Byway in the late 20th century, a period marked by landmark environmental legislation including provisions influenced by precedents like the Wilderness Act and agency planning approaches linked to the National Environmental Policy Act. Wildfire events such as the 2003 Old Fire, 2011 Pines Fire, and 2015 Lake Fire have driven successive rounds of restoration, fuel management, and interagency cooperation with organizations including the California Department of Forestry and Fire Protection and local fire districts.

Major intersections and access points

Key junctions along the route include its connection to Interstate 10 near Redlands, California and San Bernardino, California, the concurrency with California State Route 18 accessing Big Bear Lake, California, and linkage to California State Route 38 toward Highland, California and Angeles Crest Highway. Access points provide direct entry to trailheads such as the Pacific Crest Trail crossings, recreational sites like San Bernardino National Forest campgrounds, and visitor centers operated by the United States Forest Service and California State Parks. The byway also intersects regional arterial roads serving communities including Lake Arrowhead, California, Running Springs, California, Crestline, California, Arrowbear Lake, California, and logistical nodes near Victorville, California and Apple Valley, California. Emergency and service access is coordinated with agencies such as the San Bernardino County Fire Department, Caltrans District 8, and regional transit providers like the Mountain Transit Authority.

Scenic and recreational features

Scenic overlooks provide panoramas of the Mojave Desert, San Jacinto Mountains, and the Sierra Nevada foothills, with interpretive displays referencing natural history subjects like Mount San Gorgonio geology and San Andreas Fault dynamics. Recreational amenities include downhill and cross-country ski operations at Snow Summit and Bear Mountain, boating and angling on Big Bear Lake and Lake Arrowhead, California, and hiking to summits such as San Bernardino Peak and routes connecting to the Pacific Crest Trail. Wildlife viewing opportunities involve species associated with the region such as California black bear, mountain lion, and bald eagle sightings near riparian zones; birding hotspots tie into networks coordinated by organizations like the Audubon Society. Winter sports draw visitors from Los Angeles, California and the Inland Empire, while summer activities include mountain biking on trails managed by clubs affiliated with the International Mountain Bicycling Association and equestrian use facilitated through Back Country Horsemen of America chapters.

Environmental and cultural significance

The corridor traverses ecosystems ranging from montane conifer forests to sage scrub and high-desert transition zones, with plant communities including Jeffrey pine and ponderosa pine stands and conservation concerns for species tied to the California Condor recovery context and regional biodiversity planning. Cultural resources include Native American heritage sites associated with peoples such as the Serrano people and Tongva, historic resort architecture near Big Bear Lake, California and Lake Arrowhead, California, and layers of cultural landscapes shaped by logging, mining, and early tourism entrepreneurs tied to families and firms noted in regional histories. Conservation partnerships involve the San Bernardino National Forest, the California Department of Fish and Wildlife, non-governmental organizations like the Sierra Club, and local preservation groups working on habitat connectivity, erosion control, and cultural resource stewardship.

Visitor information and safety

Travelers should plan around seasonal weather influenced by Pacific storm systems and high-elevation snowpack monitored by the National Weather Service, California Department of Water Resources snow surveys, and avalanche advisories coordinated with the United States Forest Service. Road conditions and chain requirements are enforced by Caltrans and county sheriffs during winter storms; emergency services are provided through agencies such as the San Bernardino County Sheriff and California Highway Patrol. Visitor centers, ranger stations, and local chambers of commerce in Big Bear Lake, California, Lake Arrowhead, California, and Running Springs, California offer maps, permits, and trailhead information; lodging ranges from historic inns to modern resorts, with bookings managed via regional tourism offices and entities such as the Big Bear Visitors Bureau. Responsible recreation best practices align with Leave No Trace principles promoted by organizations like the Leave No Trace Center for Outdoor Ethics and local stewardship programs organized by the San Bernardino Mountains Land Trust.
