Prices, opening hours, best times to visit and the stuff nobody tells you, everything you need for a first trip to San Diego, California, plus one pigeon's opinions on all of it.
Right, San Diego. Perfect weather nearly every day of the year, excellent zoo, close enough to Mexico to feel it, a border city holding one of the most influential zoos in the world and one of the largest pop culture conventions anywhere. This is the proper, no-nonsense guide to things to do in San Diego: what things actually cost, when to go, what to skip, and which bits are worth the queue. Three main stops below, plus a quiz elsewhere on this site to see if you were paying attention.
San Diego Zoo
San Diego is home to one of the most famous zoos in the world, notable for its pioneering approach to naturalistic, cage-free enclosures, a highly influential model that changed how zoos worldwide approach animal enclosures, worth a proper full day given the scale, the zoo covers a large area with habitats designed to closely mimic natural environments.
The affiliated San Diego Zoo Safari Park, a short drive away, offers an even more expansive, drive-through style experience, worth visiting both if you have the time, each offers a different way to see the collection.
Hours Daily, roughly 9am–5pm, longer in summer
Address San Diego Zoo, Balboa Park
The Border with Mexico
San Diego sits directly on the border with Mexico, a defining piece of the region's character, Tijuana, right across the border, is reachable for a day trip if you want to see this crossing directly, worth checking current entry requirements and border wait times before planning a crossing.
This proximity shapes much of San Diego's culture and food scene, worth seeking out the strong Mexican culinary influence throughout the city, particularly in neighbourhoods like Barrio Logan.
San Diego Comic-Con
San Diego hosts one of the largest annual pop culture conventions in the world, known as San Diego Comic-Con, if your visit lines up with the convention (typically held in July), expect the city to be packed, book accommodation well ahead.
Even outside convention dates, the city's comic and pop culture shops, particularly in the Gaslamp Quarter, reflect this ongoing cultural significance, worth a browse if the scene interests you regardless of timing.
Best time Typically late July, check current dates
