Balboa Park spans an area of over 1,200 acres, which means it could take a while to see everything. Typically, it would take you at least an entire day to see the main attractions and explore the park. This could be longer or shorter depending on how much time you spend at each attraction and how much walking you want to do. It is possible to visit Balboa Park on the Old Town Trolley Tour, as it includes an overview of the park’s history, significant landmarks, and distinct architectural styles. Therefore, if you only have limited time to visit Balboa Park, you can hop on the Old Town Trolley Tour and learn about the park’s history while getting a glimpse of its beauty.
