Del Mar Fairgrounds 2260 Jimmy Durante Blvd. Del Mar, CA 92014 858-755-1161
In 1880, a group of San Diegans organized an agricultural fair to bring county farmers together to share ideas, see who had the best citrus fruit, who baked the best pie, and who had the fastest horse.
After that first fair, the county fair was held annually with a few exceptions in various county locations until 1936, when it moved to its present Del Mar home. During World War II, the fair was suspended, and has been held annually since 1946.
