The Red Triangle is a region off the coast of California, known for a high concentration of shark attacks. This area stretches from the San Francisco Bay to Monterey Bay, encompassing popular beaches like Santa Cruz and Half Moon Bay. The combination of warm waters, abundant marine life, and human activity contributes to the increased likelihood of encounters between sharks and swimmers. The name "Red Triangle" comes from the triangular shape formed by these coastal locations. Despite the fear surrounding shark attacks, they are relatively rare, and many people continue to enjoy water activities in this beautiful region.
