San Diego vs San Francisco

San Diego and San Francisco compared across the three travel tiers — budget, mid-range and luxury — for daily costs, hotels, food, things to do and the practical stuff that actually decides which one you should visit.

San Diego

United States · North America

California's southernmost city has the best weather in America and seventy miles of beaches to spend it on. Balboa Park's Spanish Revival museums, a world-famous zoo, an aircraft carrier you can walk aboard, sea lions at La Jolla and the best fish tacos north of the border — with Mexico a trolley ride away.

San Francisco

United States · North America

Seven square miles of hills, fog and Victorian terraces at the mouth of a bay — compact enough to walk in a way almost no American city is. Alcatraz out in the channel, redwoods thirty minutes north, and a food culture that runs from Mission taquerias to three-star tasting menus.
