Rules and regulations

You must be at least 48 inches tall to ride the slides.

Safety breaks

The leisure pool has mandatory 15-minute safety breaks every two hours. The safety break is designed to give kids an opportunity to calm down and acknowledge their fatigue level, use the restroom and get a break from the possible ongoing ingestion of pool water. This helps to reduce the number of incidents a lifeguard needs to respond to as well as fecal accident and vomit closures. Safety breaks start 15 minutes prior to even-numbered hours of the day, and occur every 2 hours thereafter. 


Our pool capacity is 412 persons. You may want to call first to see if the pool is at capacity before visiting, 720-733-2222.
