This 1,200-acre park is the city's cultural hub. Located in downtown San Diego (about 2 miles north of the city center), Balboa Park is a great place for a stroll, bike ride or picnic. Wander around the park's many gardens while admiring the intricate Spanish-Renaissance architecture that permeates the grounds (the best examples are the California Building and the House of Hospitality). The Botanical Building is a great starting point in Balboa Park. The building is one of the most photographed places in Balboa Park and is one of the largest lath structures in the world. But don't just look at it. The famous botanical building features more than 2,100 permanent plants, including striking collections of tropical plants and orchids. The park also features a cactus garden, rose garden, a Japanese-style garden as well as a palm tree canyon, among many others.
