It’s always a good bet toward head to the water when looking for San Diego things to do. More than 70 miles of San Diego beaches hug the Pacific, and fun activities ranging from fishing to scuba diving can be found there. But not everything in the city takes place on the water. Balboa Park is also an epicenter of San Diego attractions, encompassing 15 museums as well as the world-renowned San Diego Zoo, home to roughly 4,000 animals. During the summer, the area also hosts some of the most popular concerts in San Diego, gathering crowds together for everything from jazz to country.
