The peninsula, which is approximately long and wide, emerges from the coast to the south. It shelters the shallow, sandy Bodega Bay and the inner portion known as Bodega Harbor. Sonoma Coast State Beach comprises beaches and dunes along the south side of the promontory. The University of California, Davis runs an ongoing marine biology program at the Bodega Marine Laboratory. The laboratory is located on the grounds of Bodega Marine Reserve, which is part of the UC Natural Reserve System. The peninsula is considered a prime spot to observe the migration of whales. It is also one of the three points of the Red Triangle, a major feeding ground for great white sharks. A series of trails are a popular destination for recreational hiking.
