Facility Notices: The Longmont Y pool reopens April 16. The Arapahoe Y pool closed for bubble removal, April 24 (noon)-May 2.

Our Ys are open with newly expanded hours. Please check our reopening guide for programs that still require reservations and policies.


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.

Lap swim (for ages 12+) and family swim (Johnstown Y) are available by reservation only.


Water exercise classes are available by reservation only.


Please check our reopening guide for policies before you arrive.

Swim Lesson Flow Chart

PLEASE NOTE: Swim Starters as well as Preschool and School Age lessons under level 4 will resume in February. Private and semi-private lessons under level 4 will resume January 18. To ensure proper social distancing, parents are required to participate in lessons under level 4. Swimmers and parents stay in the water. The instructor will remain on the pool deck. Each parent will help the instructor with their child’s body position in the water to eliminate physical contact with non-family members.

Infant Swimming Resource

The Johnstown Community YMCA also offers infant swim lessons through Infant Swimming Resource (ISR). ISR lessons are designed to teach children self-rescue skills in the water through one-on-one lessons.


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.
