Tomales Bay[edit]

Tomales Bay is a long narrow inlet of the Pacific Ocean. It is approximately 15 miles (25 km) long and averages nearly 1.0 miles (1.6 km) wide, effectively separating the Point Reyes Peninsula from the mainland of Marin County. It is located approximately 30 miles (48 km) northwest of San Francisco. The bay forms the eastern boundary of Point Reyes National Seashore.
