Look, if you’re trying to find the nearest airport to Big Bear CA, you’ve probably realized that "near" is a relative term in the San Bernardino Mountains. You see a dot on the map, you think oh, that’s close, and then you realize you have to climb about 7,000 feet in elevation on roads that look like a bowl of spaghetti.
Honestly? Most people just fly into LAX because it's the biggest name, but that is often a massive mistake. You'll spend two hours just getting out of the airport traffic before you even see a pine tree.
If you want the actual, factual shortest path to the snow or the lake, you have to look at the Inland Empire and the desert.
The Real Winner: San Bernardino International (SBD)
Let's talk about the underdog. San Bernardino International Airport (SBD) is technically the closest commercial airport to the mountain base. It’s sitting right there at the bottom of the hill.
It’s about 40 miles from the terminal to Big Bear Lake.
The drive? It’s usually about an hour and fifteen minutes. You take Highway 330 up through Running Springs, and boom, you're in the village. The catch—and there is always a catch—is that SBD doesn't have a hundred flights a day. For a long time, it was a ghost town for commercial travel. Nowadays, airlines like Breeze Airways have started running routes there (SFO to SBD is a common one).
If you can snag a flight here, do it. You’ll save hours of soul-crushing Southern California freeway time.
Why Ontario (ONT) is Actually the Smart Choice
If you can't find a flight into San Bernardino, Ontario International Airport (ONT) is the gold standard for Big Bear regulars.
It’s roughly 60 miles away.
Think of ONT as the "stress-free LAX." It’s big enough to have major carriers like Southwest, Delta, and American, but small enough that you aren't going to lose your mind in a security line.
- Distance: ~60 miles
- Drive Time: 1 hour 20 minutes to 2 hours (traffic depending)
- The Route: You basically hop on the I-10 East, hit the 210, and then choose your mountain road.
The beauty of Ontario is the rental car situation. It's fast. You're in your SUV and on the 210 freeway before an LAX traveler has even found their luggage.

The Desert Route: Palm Springs (PSP)
Now, this is the one people forget. Palm Springs International Airport (PSP) is about 85 miles from Big Bear.
Wait, why would you go further?
Because of the "back way."
If you fly into Palm Springs, you can take Highway 247 through Lucerne Valley and come up Highway 18. This is the "desert side" of the mountain. It’s a much steadier, less curvy climb than the front side. If you get car sick easily or if a winter storm has shut down the main passes (Hwy 330 or Hwy 18 through Waterman Canyon), the desert route is often the only way in.
Plus, Palm Springs is just a cool airport. It’s outdoors. You walk off the plane and immediately feel like you’re on vacation. Then you drive an hour and a half and you’re in a winter wonderland. It’s a weird, California-specific flex.
What About the "Local" Airport?
You might see Big Bear City Airport (L35) on the map and think you’ve cracked the code.
You haven't. Unless you own a Cirrus or want to shell out for a private charter.
L35 is a general aviation airport. There are no commercial "buy a ticket on Expedia" flights here. It sits at an elevation of 6,752 feet. If you are a pilot, flying into here is bucket-list stuff, but the density altitude in the summer is no joke. It makes the air thin and takeoffs "interesting," to say the least.
For the rest of us, it’s just a great place to watch small planes land while you eat breakfast at the Barnstormer Restaurant nearby.
The LAX and SNA Problem
Look, I get it. Los Angeles International (LAX) and John Wayne Airport (SNA) in Orange County have the cheapest flights.
But you're paying with your time.
LAX is 100 miles away. On a map, that looks like two hours. In reality? It’s three. Or four. If you land at 4:00 PM on a Friday? God help you. You'll be sitting on the 91 or the 60 freeway watching the sun set while you're still in the concrete jungle.

SNA is a bit better—cleaner, easier—but you still have to navigate the 91 freeway, which is basically a parking lot designed by someone who hates commuters.
Which Road Should You Take?
Once you land at the nearest airport to Big Bear CA, you have three main "staircases" up the mountain.
- Highway 330/18 (The Front Way): This is what your GPS will scream at you to take. It’s the fastest but has the most "switchbacks." Great views, but keep your eyes on the road.
- Highway 38 (The Long Way): This goes through Redlands. It’s longer, but it’s a much gentler climb. It’s also way more scenic in a "forest" way rather than a "cliffside" way. Very popular with people towing trailers or those who hate heights.
- Highway 18 (The Back Way): As mentioned, this comes up from Lucerne Valley. It’s the highest point of the climb (you hit over 7,000 feet) but it’s the most reliable in bad weather.
Practical Steps for Your Trip
Don't just book the cheapest flight. You need to look at the total "time cost."
- Check SBD first: If you are coming from San Francisco or Provo, SBD is a cheat code.
- Default to ONT: For almost everyone else, Ontario is the winner.
- Rent an AWD: If you're coming between November and April, don't be the person in a Chevy Spark trying to climb a 6% grade in the snow. Even if it's sunny when you land, the mountain creates its own weather.
- Check CalTrans: Before you leave the airport, check the "QuickMap" app. It tells you if chains are required. If they are, and you don't have them in your rental, the CHP will turn you around.
Basically, the "nearest" airport is the one that gets you to the pines without a nervous breakdown. Skip LAX if you can, embrace Ontario, and always carry a pair of sunglasses for that bright mountain snow.
Before you finalize your booking, pull up a map and look at the drive from Ontario (ONT) versus LAX—that extra $50 for a flight into ONT usually pays for itself in gas and sanity by the time you reach the Big Bear dam.
