Big Sur is a sparsely populated region of the central California, United States, coast where the Santa Lucia Mountains rise abruptly from the Pacific Ocean. The terrain offers stunning views, making Big Sur a popular tourist destination. Big Sur's Cone Peak is the highest coastal mountain in the lower 48 states, ascending nearly a mile (5,155 feet/1.6 km) above sea level, only three miles (4.8 km) from the ocean.[1]

Although Big Sur has no specific boundaries, many definitions of the area include the 90 miles (145 km) of coastline between the Carmel River and San Carpoforo Creek, and extend about 20 miles (32 km) inland to the eastern foothills of the Santa Lucias. Other sources limit the eastern border to the coastal flanks of these mountains, only three to 12 miles (4.8-19 km) inland.

The northern end of Big Sur is about 120 miles (193 km) south of San Francisco, and the southern end is approximately 245 miles (394 km) north of Los Angeles.
