San Diego
Best things to do in San Diego, including free and rainy-day options
First-timers should give San Diego two or three days: one for Balboa Park's museums and gardens, one for La Jolla or Mission Beach and the coast, one for the harbour and Old Town. Skip the rental car if you stay downtown or near the bay — the trolley and coastal buses cover most of this. Add a car only for the zoo-and-north-county day.

Quick answer
San Diego rewards a short, unhurried list rather than a checklist. The city's two anchors are Balboa Park, a 1,200-acre (about 490 ha) park holding most of the museums plus the zoo, and the coast, where La Jolla, Mission Beach and Coronado each give a different day.
If you have two days: Balboa Park and downtown on day one, the coast on day two. With three days, add Old Town and Point Loma, or push north to Torrey Pines for the cliff walk. A car only pays off for the third day and beyond.
Weather decides less than you expect. San Diego is dry most of the year, but a marine layer can sit over the coast until midday in May and June — plan inland or museum time for the morning and the beach for the afternoon.

The detail
Balboa Park is the single best use of a first morning. The Prado walk, the Botanical Building and the Alcázar Garden are free, and the Museum of Us, the San Diego Museum of Art and the Fleet Science Center sit within a few minutes of each other. Pick one or two paid museums rather than trying to cover them all; the park is large and the walk between the zoo end and the museums end takes 15–20 minutes.
The zoo sits inside the park and takes most of a day. Go at opening, walk the outer loop first while it is cool, and use the Skyfari cable car to cut across. The Safari Park in Escondido is a separate site about 45 minutes north by car and needs its own day.
For the coast, La Jolla Cove is the free highlight: sea lions on the rocks, a small sheltered beach, and snorkelling or kayaking from the launch nearby. Parking is the hard part — arrive before 10am or after 4pm. Mission Beach and Pacific Beach are the boardwalk-and-rental-bike stretch, with Belmont Park's wooden coaster at the south end. Coronado is quieter: take the ferry from downtown, rent a bike, and ride the beach and the Hotel del Coronado area.
Downtown, the USS Midway Museum is an aircraft carrier you walk through, with harbour views from the deck; allow two to three hours. The Maritime Museum next door has historic ships. The Embarcadero waterfront, Seaport Village and the Gaslamp Quarter fill the rest of a downtown day, and the trolley connects downtown to Old Town and beyond.
Old Town San Diego State Historic Park is the easiest half day for anyone without a car: adobe buildings, a market square and Mexican restaurants, all on the trolley line. Point Loma's Cabrillo National Monument adds harbour and ocean views and a lighthouse, with a small entry fee per vehicle.
North of the city, Torrey Pines State Natural Reserve has cliff-top trails down to a beach; the reserve itself is free but parking is charged and fills early. Del Mar and Encinitas continue the coast north if you have a car.
What it costs
San Diego is cheaper than San Francisco or Los Angeles for the same kind of day. A two-day core trip without a car can run about US$120–180 per person in tickets if you pick the zoo plus one museum, and close to nothing if you stick to parks, beaches and the waterfront.
The big variable is transport. Parking downtown and at the beach runs about US$10–25 for a few hours, so a trolley or bus day pass is often the cheaper choice. Food is covered separately in our San Diego eating guide.

Tips
Buy zoo, Midway and SeaWorld tickets online in advance; gate prices are higher and summer entry slots sell out.
Start coastal days early. La Jolla and Torrey Pines parking is the bottleneck, not the attractions.
Keep a light jacket. The marine layer and evening sea breeze make the coast 5–10 °C cooler than inland.
Use the trolley for downtown, Old Town and the border area; it does not reach the beaches, so plan a bus or rideshare for those.
If you are here in May or June, expect grey mornings on the coast and sun 15 minutes inland — plan the beach for the afternoon.
- Book the zoo and Midway online the week before
- Park once in Balboa Park and walk, rather than moving the car
- Check sunset time before driving to Sunset Cliffs
