National Tequila Day 2026 falls on July 24 — and San Diego is one of the best cities in the country to mark it. San Diego Tequila Tour runs a guided premium tequila tasting through Old Town, the historic birthplace of California, where you'll taste five expressions of blanco, reposado, and anejo alongside expert education on how the spirit is actually made. This guide covers how to celebrate the day right.
