With beaches, ample green space, and near-perfect weather year-round, it’s no wonder the San Diego area—specifically, Chula Vista—is home to one of only three U.S. Olympic training centers. Grab a kayak at La Jolla Shores
(rental places abound) and explore the sea caves of La Jolla Cove
. Or take a walk or run along Pacific Beach
. Save time for a stroll around the San Diego Zoo
Where the athletes eat: Fuel up with a hearty, no-fuss breakfast at Kono’s Surf Club Café ($; 858/483-1669), next to Crystal Pier in Pacific Beach, where you can eat right by the water. And be sure to hit one of the many farmers’ markets around town.
