Facility Hours

We welcome you to the warm water pool at the Boulder YMCA, one of Boulder's only warm water facilities. Our warm water pool is a favorite for swimmers and not-quite-yet swimmers of all ages. With temperatures between 89 and 91 degrees, the pool keeps the shivers away for little ones learning to swim and playing in the water. The warmer temperatures also make the pool ideal for older adults who are dealing with medical conditions that affect joint or muscle integrity and adults looking for therapeutic, low-impact swimming and exercise. Join as at the Boulder Y Warm Water Pool for water walking, aquatics fitness classes, swim lessons and more.

Make the Most of Open Swim at the Warm Water Pool

Whether it's playtime or workout time, open swim times at the warm water pool offer opportunities for families, adults and seniors to move, bond, swim and exercise. During this non-structured time, our members enjoy using the pool in a variety of ways, including water walking and therapy swim as well as family time. Lap lanes are always available during open swim.


Water Walking During Open Swim

We encourage members to use the aquatic fitness equipment to achieve a vertical water workout. Water walking is an ideal way for people to rehab from injuries and to build up physical strength and endurance. This form of exercise also improves circulation, reduces the risk of falling and spares the joints. All of this — and you don’t even have to get your hair wet!

Therapy Swim During Open Swim

Designed for people of all ages for therapeutic needs, including Fibromyalgia, arthritis, debilitating diseases, recent surgeries, etc.
