The Longmont Y will be closed Aug 15-17 for annual maintenance. The pool will be closed Aug 13-17.


Join us as we open our doors to the Boulder County community, offering a safe, fun environment for families to enjoy the scariest time of year. Hundreds of spookily, adorably costumed families will converge on the Arapahoe and Longmont Ys to dance, create, jump, play and enjoy a sweet treat or two. 


Open to members and non-members. Food and some activities may require cash.
