About this swimming hole
Big River Beach sits at the mouth of the Big River under the Mendocino Headlands, where a calm lagoon meets a driftwood-covered ocean beach. The river side offers warmer, still water for swimming while the ocean side is for watching. Harbor seals haul out on the far bank, so give them space.
