The San Diego shortlist
- San Diego Zoo — the canyon zoo in Balboa Park; the Skyfari tram saves the legs, the koalas headline.
- USS Midway Museum — the aircraft-carrier deck with the restored squadrons; the audio tour is narrated by sailors who served.
- La Jolla Cove & sea lions — the cove and the bluffs; the kayaking-and-snorkel formats run from the beach.
- Coronado ferry & Hotel del Coronado — the bay crossing to the Victorian beachfront icon — the bike loop of the island is the move.
- Cabrillo National Monument tidepools — the point where Cabrillo landed; the tidepools and the whale overlook sit below the lighthouse.
Flying in, San Diego International Airport (SAN) serves the city — attraction districts sit 30–60 minutes away at typical city speeds.

Frequently asked questions
What is the number one thing to do in San Diego?
San Diego Zoo — the canyon zoo in Balboa Park; the Skyfari tram saves the legs, the koalas headline. Start there, then build the itinerary around it.
Do I need to book San Diego attractions in advance?
The headline attractions reward advance booking — timed-entry systems and quota tickets mean walk-up availability is worst exactly when you want to visit. Everything on this page links to providers showing live availability.
How many days do you need in San Diego?
Three to four days covers the shortlist above at a humane pace for a first visit; add days for the day-trip formats rather than compressing the city itself.
Is a city pass worth it in San Diego?
Run the arithmetic honestly: a pass wins when you would genuinely visit three-plus ticketed attractions in its window. Our provider links show pass options side by side with single tickets — compare before committing.
