The Maple Hill YMCA is committed to your health and community wellness. We offer a full range of programs to strengthen members in spirit, mind and body. Whether you are brand-new to exercise or a seasoned fitness fanatic, you will find freindly staff and equipment to help you meet your fitness goals. Whether you are looking to stay active, shed a few pounds or just be a part of the community, the YMCA is a great place to belong. We're focused on building a strong community around our healthy lifestyle center, as we are growing every day in membership. More importantly, however, we are growing every day in the connections we make as a family.

Our Gym is open year round to help meet all your fitness goals. Join us in the summer for some fun under the sun when our pool opens.  Come workout out with us today!
