Located along the Lost Coast shoreline, Big Flat Beach is a remote beach with light brown sand, vegetation, and pebbles. This beach is situated at the base of oceanfront mountains and is a part of King Range National Conservation Area. The Big Flat Creek flows through the beach into the Pacific Ocean. Two landforms named the Big Flat and the Miller Flat are also present around the beach. The area near the beach also has an airstrip and parcels of privately owned land.
