The offshore rock formation, Arch Rock, features a natural tunnel carved by tidal erosion.
The beach acts as a critical pupping ground for Pacific harbor seals, requiring restricted human access during spring and summer months.
The Russian River Estuary, which meets the ocean at this beach, creates a nutrient-rich brackish environment for migratory birds.
In 1985, the film 'The Goonies' famously shot its final sequence at this location, featuring the iconic Haystack Rock formation.
The beach is part of the larger California Coastal National Monument, which protects over 20,000 rocks and islands along the coastline.
Goat Rock State Beach is a coastal park located at the mouth of the Russian River, characterized by its prominent offshore sea stack known as Arch Rock. The beach serves as a seasonal haul-out site for harbor seals, which frequently congregate on the sandspit between the river and the Pacific Ocean. Due to local wildlife protection efforts, the sandspit is typically cordoned off from March through August during the pupping season. The coastline features dramatic cliffside vistas and frequent occurrences of heavy, dangerous rip currents and sneaker waves. The area provides access to the Kortum Trail, which connects to the wider Sonoma Coast State Park network. The beach is situated in Jenner, California, where the rugged terrain meets the Pacific coastline.
The overlook near the main parking area provides a panoramic view of the river mouth, Arch Rock, and the Pacific coastline.

Attempting to walk out onto the sandspit when it is closed for seal pupping, and ignoring warning signs regarding strong undertows.
The beach sandspit is closed annually from March through August to protect harbor seal pups.
Keep all dogs on a leash and strictly observe cordoned-off areas to avoid disturbing protected harbor seal populations.
