California has many amazing state parks. One is Anza-Borrego Desert State Park, not only the largest but also known for being the best stargazing destination in America. Another is the lush Humboldt Redwoods State Park, considered to be the highest-rated state park in the country. However, Old Town San Diego State Park is in a league of its own because it is a living and breathing, open-air museum that chronicles the history of the people who shaped the city’s distinctive culture.
