If you’ve only got three days in San Diego, this itinerary hits the highlights first and leaves room to slow down on your last day.
Day 1: San Diego Zoo
Start your first day at San Diego Zoo, which is the natural anchor point for a trip to San Diego and usually worth arriving early for to beat the crowds. Spend the rest of the morning exploring the surrounding area on foot before settling into a relaxed afternoon.

Day 2: USS Midway and Beyond
Day two is a good time to visit USS Midway and spend the afternoon wandering wherever your curiosity takes you — this is usually when a guided walking tour or a harbor cruise pays off, since it fills in context you’d otherwise miss on your own.
Day 3: Day Trip or Deeper Dive
Save day three for flexibility: a day trip out to Tijuana is a common choice for travelers with an extra day, but it’s just as reasonable to spend the time going deeper into San Diego itself, especially any areas you didn’t get to earlier.
