Each summer the Henry Moses Aquatic Center (HMAC) experiences a wave of visitors as nearly 75,000 people come through the gates to enjoy an assortment of splish-splash activities. Opened seasonally from mid-June through Labor Day and located in the Northeast corner of the Cedar River Park, the HMAC offers a multitude of camps, lessons, programs, and special events that intertwine fitness and water play to create an enjoyable and relaxing atmosphere.

Through our diverse audience a variety of suggestions have been made in regards to the operations of the park. By analyzing these comments from past seasons, modifications have been implemented that we’re excited for you to experience. We will continue to collect feedback throughout the 2018 season as we strive to improve your experience at the HMAC.

Hours and Rates

As you can imagine the HMAC is a popular destination during the summer and at times maximum capacity may be reached. Due to fire code, the HMAC will halt admission when this occurs, once maximum capacity has subsided admission will continue.

General Admission sales begin at 9 a.m. and all sales are final, good for day of purchase only, and refunds will not be issued for unused tickets (including unused tickets due to fire code capacity).

Additionally, General Admission does not include Friday Night Lights which must be registered for admittance into the aquatic center.

In order to receive the resident discount admission price, proof of residency is required.
