Check out our updated summer schedule, effective for the 2018 summer season.

Each summer roughly 75,000 visitors come through the gates of Henry Moses Aquatic Center (HMAC). With this comes an equally diverse and variety of suggestions to be made to the operations of the park. Therefore we’re excited for you to experience the changes made based on those suggestions. We will be collecting feedback throughout the season and at the end of the summer to analyze changes made and consider additional changes. We will continue to improve experiences provided by HMAC for Renton residents and the regional customers we serve.
