San Diego Things To Do: San Diego is California's second-largest city, so seeing all the city has to offer is no small feat. Hop on a Trolley Tour to avoid driving and parking and get treated to local knowledge and witty anecdotes from their knowledgeable tour guides.
San Diego Trolley Tours offers day tours to the best sites in the city, and allows you to hop on and off at your own convenience. For even more of an adventure, you can take a Seal Tour aboard an amphibious vehicle that starts on land and then plunges into the bay for a tour of the harbor.
