Discover a fascinating chapter in California history during a visit to Mission San Luis Rey, located just north of the San Diego downtown. This admission, valid daily between 10am and 4:30pm, includes access to the on-site museum, mission grounds, and a self-guided tour, during which you can explore the National Historic Landmark at your own pace. Founded in 1798, Mission San Luis Rey was once known as “King of the Missions.” Among the largest and most prominent of the 21 Spanish missions located across California, it’s famous for its sprawling lavanderia archaeological site, as well as its sunken gardens, wooden dome and cupola, and other unique architectural features. In the museum, discover Native American, Spanish, and Mexican artifacts, and learn about the history of Spanish influence in California. Today, the mission doubles as a home to Franciscan friars and is a functioning retreat center; its church celebrates daily Mass at noon, which visitors are also welcome to attend.
