arapahoe y pool in lafayette

The Arapahoe YMCA Pool in Lafayette, Colorado is a year-round, indoor/outdoor pool that welcomes all to become stronger, more confident swimmers. During the winter, the Arapahoe Y pool is covered with our bubble, which is taken down between mid-May and late September. In the summer, the Arapahoe Y pool is a sun seeker's paradise — with slides, diving boards, a zero-depth baby pool, sand volleyball court and splash pad. Before families enjoy a fun day of playing, jumping and splashing in the water, we encourage both members and Lafayette residents to join us for swim lessons for kids, teens and adults. If you are looking to bring your workout into the water, the Arapahoe Y pool offers Aqua Zumba and numerous opportunities for lap and open swim. Check the schedules page for details. And if your kids are interested in water recreation opportunities, the Arapahoe Y pool hosts swim teams.
