Friendly strangers, 70-degree sunshine and a zoo that ranks among the best on the planet: San Diego has just been crowned the friendliest city in the United States, scoring 8.67 out of 10 in a 2025 survey by social app Yuzu, which rated how positively locals interact with strangers and how willing they are to help. If you've been weighing up a Southern California trip, this is a decent tiebreaker.

Start at Balboa Park, a 1,200-acre spread of gardens, playgrounds and public art you can explore for free (there's a carousel and miniature train if you want to spend a little). The park also houses the Comic-Con Museum for pop-culture fans and the hands-on Fleet Science Center for curious kids. Next door sits the famous San Diego Zoo, home to cloud leopards, fossa, sun bears and hamadryas baboons, plus an aerial tram and guided bus tour — easily a full day out. Its sister Safari Park in Escondido, about 35 miles away, gets you closer to giraffes and rhinos, while Birch Aquarium on the north end adds leopard sharks, loggerhead turtles and a giant Pacific octopus to the list.

Theme park families are spoiled too. Belmont Park in Mission Beach has been running its wooden Giant Dipper roller coaster for over a century, alongside bumper cars, mini-golf and a laser maze. Sesame Place in Chula Vista, 16 miles south, caters to toddlers with rides and live shows, and Legoland California in Carlsbad, 33 miles north, is the pick for young builders — complete with a Lego factory tour.

Then there are the beaches. Coronado Beach is the family favourite, with wide sand, tide pools and the odd bonus of low-flying military jets approaching Naval Air Station North Island at the northern end. Mission and Pacific Beach share a long connected boardwalk lined with food and shops, while La Jolla Cove offers a rockier, wilder scene where you can swim, snorkel and watch seals and sea lions up close.

Getting there is simple: fly into San Diego International (SAN) or drive down I-5 from Los Angeles, roughly two to three hours depending on traffic. Accommodation spans every budget — downtown chains near Balboa Park from around $100 to $200 a night, the walkable Gaslamp Quarter with options from the historic Horton Grand to the modern Alma San Diego Downtown, or beachside stays from Mission Beach up through La Jolla. With friendly locals as the default setting, it's an easy sell for a first family trip to California.
