Looking for a fun, supportive environment where your child can improve their swimming while bonding with neighborhood friends? Look no further than the Columbia Neighborhood Swim League (CNSL), which remains a beloved tradition for generations of families in our community. 

This summer recreational swim league is open to swimmers ages 18 and younger of all ability levels. There are no tryouts required, however, swimmers younger than age 10 must be able to swim the length of one pool, and swimmers age 11 and up must be able to swim two lengths of the pool. There are 14 swim teams located throughout the Columbia, Ellicott City, and Clarksville areas. 

CA provides coaches, facilities, and a framework for CNSL participants to improve swimming abilities, develop good sportsmanship, and test performance in actual competition as part of a team in a safe and encouraging learning environment.
