Our Ys are open with temporarily reduced hours to members and program participants. Guests are now welcome. Please check our reopening guide for policies before you arrive.


For children from 6 months to 3 years old, YMCA Swim Starters swim lessons help children become comfortable in water and teach parents about water safety. These lessons do not teach children how to survive in water or become accomplished swimmers. Instead, Swim Starters swim lessons create a foundation of aquatic skill through fun and confidence-building experiences. Parents and caregivers learn how to supervise children in water, prevent accidents and plan for emergencies. These lessons are held in Boulder, Lafayette, Longmont and Johnstown.

The pools are now open for open swim, lap swimming, water fitness classes, swim lessons and Masters Swim.

Lap swim and water exercise classes are available by reservation only.

Open swim and family swim are available for reservation only through Appointment Plus.

Please review our reopening guide so you know what to expect.

Registration closes three days prior to the lesson start date to give us time to coordinate each lesson. If you would like to sign up for lessons after registration closes, please call the Aquatics Department to see if space is still available.
