San Juan Bautista is not in California's coastal region.
The town sits in the San Juan Valley between the Gabilan Range (east) and Santa Cruz Mountains (west). The San Andreas Fault runs through the valley.
Coastal classification affects climate (less fog, greater diurnal range), agriculture (wine, row crops), tourism (mission-focused vs. beach), and planning jurisdictions.
Mission San Juan Bautista (1797) — 15th California mission, on the historic El Camino Real, adjacent to the only original Spanish plaza remaining in California.
