The destination of Twin Peaks is a good option if you’ve been considering a getaway with the kids. The sledding, camping sites, and lake views are just some of the things that make this the perfect spot for family trips. Arrange a flight into San Bernardino, CA (SBD-San Bernardino Intl.), which is the closest airport, or Los Angeles - Ontario Intl. Airport (ONT), which is located 23.7 mi (38.1 km) from the city center.
