San Diego, United States Itinerary: 3 Perfect Days
San Diego rewards a slower pace than most US cities: the highlights are spread along the coast, and the drive between them is part of the day. This plan pairs one big attraction with one stretch of coastline each day.
March to May and September to November are the sweet spots. Late May and June often bring 'May Gray' and 'June Gloom' — a coastal marine layer that burns off by early afternoon.
Getting around
A car is the easiest option for La Jolla and Coronado; downtown, Balboa Park and the waterfront are walkable, and the MTS trolley links the Gaslamp Quarter with Old Town.

Practical tips for San Diego, United States
Coastal parking fills by mid-morning in La Jolla and Coronado on weekends — arrive before 9am or use a paid lot.
The marine layer usually clears after noon, so schedule beach time for the afternoon in late spring.
Ocean water stays cool year-round; a wetsuit is normal for surfing even in August.
A multi-attraction pass only pays off if you visit the zoo and at least two other ticketed sights.
San Diego, United States itinerary questions
Do I need a car in San Diego?
For this plan, yes — La Jolla, Torrey Pines and Point Loma are awkward without one. A downtown-only trip can be done with the trolley, ferry and rideshares.
Is 3 days enough for San Diego?
Three days covers Balboa Park, the La Jolla coast and Coronado. Add a fourth day if you want both the zoo and a full theme-park visit.
What is the cheapest time to visit San Diego?
January to March, outside holiday weeks, is the quietest and cheapest window, with mild but occasionally rainy weather.
