Shell Beach lies just south of Boomer Beach. It is a small beach and includes Seal Rock, a big rock offshore where California sea lions like to gather. It's a great spot for shell collecting and tide pool exploring at low tide, and for those who prefer an uncrowded beach. Small children like to wade at Shell Beach, but because the reef comes right up to the shoreline, swimming should be restricted to strong swimmers only. Snorkeling is popular in the beautiful reefs and deep waters just offshore. Body-boarding and surfing are not allowed. Lifeguards are on duty. Restrooms and showers are available at the Children's Pool.
