Eastern Long Island boasts some of the Northeast’s most captivating beaches, perfect for summer fun. However, parents of young children may want to invest in swimming lessons from qualified instructors in order to put themselves at ease amid all the oceanside activity. Happily, there are some affordable kids' swim programs on both forks. Classes do fill up quickly, though, so you'll want to enroll your children ASAP.

Note: Most town-sponsored, outdoor programs begin in July. YMCA and Southampton Youth Services programs continue year-round.
