Big Sur is a rugged and mountainous section of the Central Coast of the U.S. state of California, between Carmel Highlands and San Simeon, where the Santa Lucia Mountains rise abruptly from the Pacific Ocean. It is frequently praised for its dramatic scenery. Big Sur has been called the "longest and most scenic stretch of undeveloped coastline in the contiguous United States", a sublime "national treasure that demands extraordinary procedures to protect it from development", and "one of the most beautiful coastlines anywhere in the world, an isolated stretch of road, mythic in reputation". The views, redwood forests, hiking, beaches, and other recreational opportunities have made Big Sur a popular destination for visitors from across the world. With 4.5 to 7 million visitors annually, it is among the top tourist destinations in the United States, comparable to Yosemite National Park, but with considerably fewer services, and less parking, roads, and related infrastructure.

The Central Coast is an area of California, roughly spanning the coastal region between Point Mugu and Monterey Bay. It lies northwest of Los Angeles and south of the San Francisco Bay Area, and includes the rugged, rural, and sparsely populated stretch of coastline known as Big Sur.
