Since 1995, Summer swimming at the Bel Air Athletic Club has been a fun and exciting way to spend your summer. The BAAC Swimming Summer Swim Team is a proud member of the Harford Swim League (HSL). Our swim team is open to swimmers from 5-18 years of age and offers instructional and competitive swimming for all age groups. The HSL season is only two months long, June and July, but it is packed with lots of fun, excitement, and lasting memories. HSL includes teams from all over Harford County Maryland.
