4 Best Sights in San Diego, California

San Diego's monument to sports and fitness, this 4,600-acre aquatic park has 27 miles of shoreline including 19 miles of sandy beaches. Playgrounds and picnic areas abound on the beaches and low, grassy hills. On weekday evenings, joggers, bikers, and skaters take over. In the daytime, swimmers, water-skiers, paddleboarders, anglers, and boaters—some in single-person kayaks, others in crowded powerboats—vie for space in the water.

Adjacent to San Diego's County Administration Center is one of the city's most playful destinations—this 12-acre, family-friendly space is a great place to stretch out and cool off with fountain jets that are operational during the warmer months and a playground where children can climb, swing, and slide to their hearts' content. Even if you're just taking a moment to rest, the seaside view is worth the stop.

The hillsides of the 50-acre green space overlooking Old Town from the north end of Taylor Street are popular with picnickers, and many couples have taken their wedding vows on the park's long stretches of lawn, some of the greenest in San Diego. The park offers a great ocean view from the top, and more than 2 miles of hiking trails below. It's a nice walk from Old Town to the summit if you're in good shape and wearing the right shoes—it should take about half an hour. You can also drive to the top of the park via Presidio Drive, off Taylor Street.

If you walk, look in at the Presidio Hills Golf Course on Mason Street. It has an unusual clubhouse that incorporates the ruins of Casa de Carrillo, the town's oldest adobe, constructed in 1820. At the end of Mason Street, veer left on Jackson Street to reach the presidio ruins, where adobe walls and a bastion have been built above the foundations of the original fortress and chapel. Also on-site is the 28-foot-high Serra Cross, built in 1913 out of brick tiles found in the ruins. Continue up the hill to find the Junípero Serra Museum, built at the sight of the original Mission San Diego de Alcalá and often mistaken for the mission. Open weekends, the Serra Museum commemorates the history of the site from the time it was occupied by the Kumeyaay Indians through its Spanish, Mexican, and American periods. Then take Presidio Drive southeast to reach the site of Fort Stockton, built to protect Old Town and abandoned by the United States in 1848. Plaques and statues also commemorate the Mormon Battalion, which enlisted here to fight in the battle against Mexico.

Kids will love the playgrounds at Trolley Barn Park, just around the corner on Adams Avenue. The park is also home to free family concerts in the summer.
