Overview
Angeles National Forest is a federally managed forest covering roughly 700,000 acres across the San Gabriel Mountains north of Los Angeles. It sits within Los Angeles and San Bernardino counties and serves as the primary wildland recreation area for one of the most populous metro areas in the United States.
Elevations range from around 1,200 feet in the lower canyons to over 10,000 feet at Mount San Antonio (Mount Baldy), the highest peak in the range. This dramatic relief means the forest can offer snow-dusted peaks and sunny chaparral slopes in the same day.
Because it is managed by the U.S. Forest Service, most of the forest is open to the public without entrance fees for day use on most trails, though certain developed recreation areas and campgrounds charge fees. It is worth noting that the forest has experienced significant fire damage in recent years, and closures or trail conditions can change with little notice.
The forest is not a city or town — it has no urban center, hotels, or restaurants within its boundaries. Visitors base themselves in surrounding communities such as Pasadena, Azusa, Monrovia, La Cañada Flintridge, Wrightwood, or the city of San Bernardino.
Before You Go
Adventure Pass and Permits
Many trailheads and developed day-use areas in Angeles National Forest require a valid National Forest Adventure Pass displayed in your vehicle. Annual and daily passes are available; verify current pricing and participating locations on the U.S. Forest Service website or at local ranger stations and outdoor retailers before your visit.
Fire Closures and Trail Conditions
California's fire seasons have grown longer and more severe. Portions of the forest may be closed due to active fire risk, post-fire debris flow hazard, or rehabilitation needs. Always check current closure orders on the Angeles National Forest official site (fs.usda.gov/angeles) before setting out.
Permits for Wilderness Areas
Overnight camping in designated Wilderness areas — including the San Gabriel Wilderness and the Sheep Mountain Wilderness — may require a free or fee-based wilderness permit. Check requirements at the relevant ranger district. Quotas can apply on busy weekends.
Weather Awareness
- Summer temperatures in lower canyons can exceed 100°F (38°C); carry more water than you think you need.
- Winter storms can close mountain roads (notably Angeles Crest Highway / CA-2) with little warning.
- Check Caltrans road conditions and the National Weather Service forecast for the San Gabriel Mountains before driving or hiking.
Cellular Coverage
Coverage is patchy to nonexistent across much of the forest. Download offline maps (e.g., Gaia GPS, AllTrails) and inform someone of your planned route before you leave.
Getting There
By Car
The forest is most practically accessed by private vehicle. Key entry routes include:
- Angeles Crest Highway (CA-2) from La Cañada Flintridge — the main scenic corridor through the San Gabriel Mountains
- San Gabriel Canyon Road (CA-39) from Azusa — leads to Morris and San Gabriel Reservoirs and upper canyon trailheads
- Big Tujunga Canyon Road from Sunland/Tujunga
- Mount Baldy Road from the city of Upland or Claremont for the eastern section
Driving time from downtown Los Angeles varies from roughly 45 minutes to 1.5 hours depending on origin and destination within the forest, plus traffic.
By Public Transit
Limited bus service from Metro and Foothill Transit reaches the forest's lower edges near Azusa (Gold Line / A Line station at Azusa Downtown). From there, trailheads are generally not walkable — you would need a rideshare or bicycle to cover the remaining distance. Visitors without a car should plan carefully and verify current service schedules with the relevant transit agency.
Nearest Airports
- Los Angeles International Airport (LAX) — approximately 40–60 miles from most trailheads
- Bob Hope Airport / Hollywood Burbank Airport (BUR) — often more convenient for the western and central sections of the forest
Getting Around
A personal vehicle is effectively required for most visits. The forest spans a large and rugged area, and trailheads are spread across numerous roads that are not served by public transit.
Angeles Crest Highway (CA-2) is the primary scenic drive, connecting many of the most popular trailheads, picnic areas, and viewpoints. The road is subject to seasonal and storm-related closures — verify conditions before driving it end-to-end.
Mountain biking is permitted on many fire roads throughout the forest, and dedicated multi-use trails exist in areas like Millard Canyon and the Gabrielino Trail. Cyclists should check which surfaces allow bikes, as single-track trails in Wilderness areas are typically restricted to foot travel only.
Things to See & Do
Hiking
Angeles National Forest contains hundreds of miles of trails ranging from gentle streamside walks to strenuous peak ascents. Some well-regarded routes include:
- Mount Wilson Trail (from Sierra Madre) — a historic and challenging climb to the Mount Wilson Observatory
- Switzer Falls (off CA-2) — a popular moderate waterfall hike, though the canyon has been affected by fire; check current access
- Gabrielino National Recreation Trail — follows the West Fork of the San Gabriel River through shaded canyon terrain
- Mount San Antonio (Mount Baldy) — the highest peak in the range at 10,064 feet; accessed via Baldy Notch with trail options for different skill levels
- Charlton Flat and Chilao Flat — gentler terrain suitable for families
Camping
Developed campgrounds are managed by the U.S. Forest Service and some through concession operators. Sites at Buckhorn, Chilao, Coulter Group Camp, and Crystal Lake are among those historically available. Reserve early through Recreation.gov, especially for spring and summer weekends.
Snow Play
In winter, areas near Big Pines and Wrightwood see significant snowfall. Ski resorts Mountain High operates nearby (verify current operations independently). Designated snow play areas may require an Adventure Pass.
Rock Climbing
The forest has well-established climbing areas, including Williamson Rock (access has been subject to raptor nesting closures — verify before visiting) and areas near Islip Saddle.
Fishing and Swimming
The San Gabriel River's East and West Forks are popular for catch-and-release trout fishing and wading. California fishing regulations and a state fishing license apply — verify rules with the California Department of Fish and Wildlife.
Practical Information
Ranger Stations
The forest is managed across multiple ranger districts. Key offices include the Arroyo Seco Ranger District (La Cañada Flintridge), San Gabriel River Ranger District (Glendora), and Front Country Ranger District. Contact information and addresses are available on the official U.S. Forest Service website; call ahead to confirm hours.
Emergency Services
In an emergency, call 911. Cellular service is unreliable in much of the forest, so satellite communicators (such as Garmin inReach or SPOT) are recommended for backcountry trips. Search and rescue operations in Los Angeles County are conducted by the Los Angeles County Sheriff's Department.
Leave No Trace
Pack out all trash. Campfires are restricted or prohibited depending on current fire danger — check fire restrictions posted at trailheads and on the forest website. Human waste must be packed out or buried well away from water sources in many areas.
Toilets and Water
Developed campgrounds and some picnic areas have vault or flush toilets. Backcountry water sources (streams) should be filtered or chemically treated before drinking. Do not rely on streams being flowing year-round, especially in late summer.
Safety
Wildfire and Post-Fire Hazards
Fire risk is the most serious safety concern in the forest. After major fires, burned slopes become prone to flash flooding and debris flows during rainstorms. Avoid canyon bottoms during or after heavy rain in recently burned areas, and monitor local emergency alerts.
Heat and Sun Exposure
Summer canyon temperatures can be extreme. Start hikes early in the morning, carry at least two liters of water per person for a moderate day hike (more in summer), and know the symptoms of heat exhaustion and heat stroke.
Wildlife
Black bears are present in the forest. Store food in hard-sided containers or bear boxes at campsites; never leave food in your car in visible reach. Rattlesnakes are common on rocky and brushy trails — watch where you step and place your hands. Mountain lions are present but rarely encountered.
Trail Navigation
Many trails are not well-signed. Download a reliable offline mapping app and carry a paper map if venturing far from trailheads. Inform a contact of your plans and expected return time.
