About this place
San Bernardino is a large, diverse city in California's Inland Empire, east of Los Angeles. Its population reflects a significant Hispanic and Spanish-speaking community, and it serves as a regional hub for the surrounding county. The area experienced major economic shifts after the decline of local steel manufacturing and the closure of a nearby Air Force base in the 1990s. Recovery has been slow, marked by a high-profile municipal bankruptcy from which the city only emerged in 2017.
Today, visitors will find a walkable and lively downtown core with angled parking, lower vehicle speeds, and a mix of shops, festivals, and restaurants. The city's historic main street charm is a highlight, though the broader destination is still redefining itself as a tourism stop.

Planning Tips
- Getting around — The city is easily navigable by freeways I-210, I-10, I-215, and I-15. A personal car or rideshare is the most practical way to travel, as intercity bus stations and points of interest are spread out.
- Train connections — The Metrolink San Bernardino Line provides direct rail service to downtown Los Angeles, and Amtrak's Southwest Chief stops at the historic Santa Fe Depot on its long-distance route.
- Flying in — The most convenient commercial airport for regular flights is LA/Ontario International Airport, just west of the city. It is typically a less congested and more affordable option than Los Angeles International Airport (LAX), which is farther away.
- Be ready for heat — If visiting in summer, plan indoor or early-morning activities and stay hydrated. Afternoon temperatures can escalate quickly.
