Cockle Cove Beach

Tucked into the sheltered southwest corner of Chatham, Cockle Cove Beach sits along Nantucket Sound and delivers exactly what families and calm-water seekers are after: warm, shallow water, a gradual sandy bottom, and the kind of low-key beach day that feels genuinely restorative. Because it faces south onto the Sound rather than the open Atlantic, the surf here stays gentle and the water temperature climbs notably higher than on the ocean side — a real bonus for kids and anyone who wants to actually swim rather than just brace against waves. Shallow, marsh-fed, warm — the family-with-toddlers pick.
