Balboa Park is home to the San Diego Zoo, numerous museums and more than 68 miles of beautiful beaches in and around the city.

A real must-see is San Diego’s Seaport Village, which contains many unique shops and restaurants, and is a pleasant stroll on any day. On the San Diego Waterfront Trail, visitors can take a self-guided tour of the USS Midway, a nautical museum.
