How to Check Big Bear Road Conditions Before Your Trip
We recommend checking road conditions several days before your visit, again the evening before departure, and once more immediately before leaving.
Three Main Routes to Big Bear Lake
Big Bear Lake can be reached by three scenic mountain routes. The best option depends on where you’re traveling from, current highway conditions, and your comfort with mountain driving.
Highway 330 and Highway 18 Through Running Springs
Highway 330 connects the San Bernardino Valley with Running Springs, where travelers continue toward Big Bear on Highway 18.
Best for: visitors traveling from Los Angeles, Orange County, and the Inland Empire.
The drive features mountain scenery, winding roads, and significant elevation changes. Traffic can become heavy during weekends, holidays, and busy winter periods.

Highway 18 Through Lucerne Valley
Highway 18 provides an approach to Big Bear from the High Desert through Lucerne Valley.
Best for: Visitors approaching from the High Desert or travelers evaluating an alternate route based on current conditions.
This route is often considered by visitors coming from Victorville, Barstow, Las Vegas, and surrounding desert communities. It may also be an alternative when other mountain approaches are affected by closures.
Although it approaches Big Bear from a different direction, it still includes mountain grades, curves, and potentially icy or snowy roadways.

Highway 38 Through Redlands and Mentone
Highway 38 provides another scenic route into the Big Bear Valley, traveling through the San Bernardino Mountains from the Redlands and Mentone area.
Best for: Visitors approaching from Redlands, Mentone, and nearby communities when the highway is open and conditions are suitable.
This route passes through forested mountain landscapes and is sometimes considered by visitors who prefer an alternative to the Running Springs approach.
Highway 38 may be affected by construction, storm damage, maintenance, or weather-related restrictions.
Travel tip: No single highway is guaranteed to be the fastest or safest in every storm. Always choose your route based on current official road conditions.

Do You Need Snow Chains to Drive to Big Bear?

Yes, snow chains or approved traction devices may be required when winter conditions affect mountain highways.
Even vehicles equipped with four-wheel drive or all-wheel drive may need to carry traction devices when entering chain control areas.
Requirements depend on the posted restrictions, vehicle type, tires, and current road conditions.
Understanding California Chain Control Levels

Always follow posted signs and instructions from Caltrans or the California Highway Patrol.
For full requirements and exceptions, visit Caltrans Chain Control Information.
Can You Drive to Big Bear with AWD or 4WD?
Yes, many visitors travel to Big Bear in all-wheel-drive or four-wheel-drive vehicles. However, having AWD or 4WD does not eliminate the need to prepare for snow and ice.
Depending on conditions, you may still be required to carry or install approved traction devices.
Check your vehicle manufacturer’s instructions before purchasing or installing chains, as some vehicles have specific clearance restrictions.
Winter Driving Tips for Big Bear
Winter in Big Bear can bring beautiful snowy landscapes, but mountain driving requires preparation.
Before traveling during winter weather, make sure your vehicle is ready for cold temperatures, changing visibility, and potentially slippery roads.
Your Mountain Driving Checklist
- Check tire tread and tire pressure.
- Inspect brakes, windshield wipers, headlights, and defrosters.
- Carry compatible tire chains or approved traction devices.
- Practice installing chains before your trip.
- Keep your fuel tank adequately filled or your EV sufficiently charged.
- Bring water, snacks, warm clothing, and blankets.
- Pack a flashlight, ice scraper, gloves, and a small shovel.
- Allow extra travel time.
- Reduce your speed and increase following distance.
- Avoid sudden braking or sharp steering on snow and ice.
Whenever possible, plan your mountain drive during daylight hours, especially if you’re unfamiliar with the roads.
Watch for Ice, Fog, and Changing Conditions
Mountain weather can change rapidly, and roads may become slippery even when snowfall has stopped.
Shaded areas, bridges, and higher elevations can remain icy after nearby pavement has dried.
Fog may also reduce visibility, while fallen rocks and storm debris can create additional hazards.
Drive cautiously, use designated turnouts when appropriate, and never stop in active traffic lanes to take photos or play in the snow.
What Happens If Roads to Big Bear Close?
Road closures may occur because of winter storms, traffic accidents, maintenance, construction, or other safety concerns.
If your planned route closes, check Caltrans for current restrictions and available alternatives. Do not assume another mountain highway is open without confirming its status.
If all practical routes are affected, wait until conditions improve rather than attempting an unsafe detour.
