California Citrus State Historic Park
A living tribute to the citrus boom that built Southern California, with hundreds of orange, lemon, and grapefruit trees, period architecture, and interpretive trails. Walk the fragrant groves, learn the region's agricultural history, and pick up fresh-squeezed juice — a quietly charming, distinctly Californian stop.
