The Story Behind California’s Red Triangle Is Terrifying But True

California is famous for its gorgeous beaches, but there’s a particular stretch of ocean that has a bloody reputation.

California’s “Red Triangle” is the site of over 1/3 of great white shark attacks. The danger zone begins around Bodega Bay and extends south about 50 miles west of San Fransisco. The triangle juts out beyond the Farallon Islands and down to Big Sur south of Monterey. The triangle encompasses about 200 miles of coastline.

Swimmers and surfers enjoying the waters of the Red Triangle are urged to stay alert and use good judgement. Check out this video from National Geographic for more information about the Red Triangle.
