San Diego began with the Kumeyaay, thriving on land and sea resources. Spanish settlers arrived in the 1700s, establishing missions, and the city evolved into a key port. Today, it’s a relaxed destination, famous for its beaches, naval presence, and easygoing atmosphere. Historic Spanish architecture blends seamlessly with modern breweries, creating a vibrant, diverse scene. From coastal beauty to cultural landmarks, San Diego offers a unique, laid-back charm that invites exploration and enjoyment for visitors and locals alike.
