Visit Ontario/LA.

Situated roughly at the halfway mark between downtown Los Angeles and San Bernardino against a backdrop of stunning snowcapped peaks, Ontario International Airport offers travelers convenient access to both bustling cities and breathtaking wilderness.

Those looking to take a wintertime trip slope-side will be spoiled for choice. The San Bernardino Mountains that lie just beyond the city of the same name offer attractive options for skiers and snowboarders of all skill levels among the peaks that surround the blue waters of Big Bear Lake. Likewise, the heights of the San Gabriel Mountains located just north of Ontario/LA are ripe for racing down, but those that prefer to take in the valley vistas at a more comfortable pace will find plenty of runs that are to their liking among the area’s resorts.

That’s not to say the region doesn’t also make for a spectacular summertime destination: Those same mountain ranges attract both nature lovers and thrill-seekers. Take a hike beneath old-growth pines or climb and canyoneer among the parks’ craggy natural features. Not looking to be too active? Who could be faulted for taking it easy and enjoying an idle picnic near the natural beauty of Angeles National Forest? Those inclined toward leisure will of course find even more to enjoy here beyond lunchtime, like lazing in shallow pools of the San Gabriel River beneath the almost ever-present California sun.

Once you have had your fill of the great outdoors (if you ever do, that is), take your pick of the region’s cities. Boasting a population of 13 million-plus, the seemingly boundless Los Angeles metro area is jam-packed with action and attractions, from Malibu to Laguna Beach, North Hollywood to South Park, plenty of which can be found within Los Angeles itself. Visitors can see the City of Angels all at once from the heights of Griffith Park, or savor it bit by bit as they take in the cultures and take down the cuisines of Koreatown, Chinatown, and Little Tokyo. All these neighborhoods and more encircle Downtown Los Angeles, home to the Fashion District, epicenter of world style, and The Broad, a contemporary art museum that boasts an eye-catching exterior to match the many works it houses.

Whether it’s exploring the outdoors, sightseeing in the cities, or a bit of both that brings you out to the Los Angeles area, make your way there with ease by catching a flight to Ontario International Airport on Southwest Airlines. Find flights to Ontario/LA with Southwest® and book your SoCal sojourn with ease today.
