San Bernardino sits at the foot of the San Bernardino Mountains in California's Inland Empire, around 60 miles east of Los Angeles. It's a city with genuine Route 66 heritage, warm year-round weather and easy access to both desert scenery and alpine resorts, making it an interesting alternative to the more crowded coastal cities for UK travellers who want sunshine, history and outdoor adventure in one trip.
Spring (March to May) and autumn (September to November) offer the most comfortable conditions, with warm days, low rainfall and clear mountain views. Summer temperatures regularly climb above 35°C, which suits sun-seekers but can feel intense for sightseeing. Winters are mild in the city itself, while the nearby San Bernardino Mountains see snowfall, making this a handy base for a ski trip to Big Bear or Lake Arrowhead. For the best fares, check the When to book chart above, as prices to this region shift with the seasons.
There are no non-stop flights from the UK to San Bernardino. The standard route is a direct flight from London to Los Angeles International (LAX) with British Airways or Virgin Atlantic, taking around 11 hours, followed by a road transfer or short domestic hop to San Bernardino, roughly an hour's drive away. Travellers connecting via other US hubs with airlines such as American Airlines, Delta or United can also route through Ontario International Airport, which sits closer to San Bernardino than LAX. Comparing both options on the price charts on this page will help you find the fastest and cheapest combination for your dates.
Beyond its role as a gateway to the mountains, San Bernardino has plenty to keep visitors busy for a day or two before heading further afield.
San Bernardino International Airport occupies the former Norton Air Force Base site, about three miles east of downtown. It handles general aviation, cargo and limited scheduled passenger flights, so most UK travellers will arrive via LAX or Ontario and complete the journey by hire car, rideshare or shuttle. From SBD itself, taxis and rideshares reach the city centre in around 10 minutes; from LAX, allow 90 minutes to two hours by road depending on traffic, and around 45 minutes from Ontario.
UK passport holders need a valid ESTA authorisation under the Visa Waiver Programme for stays of up to 90 days, applied for online before departure. The currency is the US dollar; card payments are widely accepted, though it's worth carrying some cash for smaller purchases. Comprehensive travel insurance with medical cover is strongly recommended, as healthcare costs in the US can be high, and a passport valid for the full duration of your stay is required for entry.
