San Diego embodies the Southern California lifestyle in many ways, with a relaxed, low-key vibe that's unique among major American cities. Here you’ll find miles of sandy beaches and imposing headlands, fantastic restaurants and lively bars, and the oldest Spanish settlement in modern-day California, now simply known as San Diego’s Old Town. Many of the best things to do in San Diego are centered around sprawling Balboa Park, from the anthropology-focused Museum of Man to the globally celebrated San Diego Zoo. And for optimal exploring, San Diego tours include everything from trolley excursions to harbor cruises.
There are things to do in San Diego all year-round. Here, the weather is generally warm and the sun most likely will be shining. Its cool season is December–March, but even then temps are mild. Summer and school winter holidays bring more tourists, especially at the beaches. To avoid the rush, visit in the spring or fall.
Downtown San Diego and surrounds have a convenient trolley system that connects to the city's bus system. That said, San Diego is a sprawling city, so the most convenient way to get around is usually via car. Rideshares like Uber and Lyft and e-scooter rentals are options, too. The Coaster commuter rail service is a public transit mainstay, with eight stops between San Diego to Oceanside.
Embrace the water when visiting San Diego. You can take a sailboat on the San Diego Bay, go on a kayak tour, or ride a sea bike in Mission Bay or La Jolla Cove. You can also spot maritime highlights like the Star of India, or surf just about anywhere along the coast. Remember, the water is chilly, with average summer temps of about 67°F (19°C). Reward yourself with SoCal specialties like fish tacos and margaritas.
