Alligator's Creek logo

Located in O'Fallon's Civic Park, Alligator's Creek is one of the finest outdoor aquatic centers in the area with exciting features for all ages.

U.S. Coast Guard-approved flotation devices only, please.

Renovations before the 2018 season expanded the aquatic center to twice its original size. Among the new features are a comfortable modern bathhouse, a new concession stand, a longer lazy river with a zero-depth beach entrance, an exciting new splash pad for kids of all abilities, a floating bridge and a new pool with a fun waterway that connects a larger pool with a newly-installed interactive water playground. Also new for 2018, the pool will open an hour earlier each day at 11 a.m.

In addition, the complex still offers three water slides, each in a different style, a one-meter spring diving board, a family-friendly whirlpool or vortex, and a swimming pool with lap lanes. This outstanding community aquatic complex offers patrons a choice of daily admission or season passes, exciting promotional days, swim lessons, birthday parties and facility rentals.

The facility is open from Memorial Day weekend to Labor Day weekend. See the Aquatics section of the Spring or Summer Parks & Rec Guide for season passes, rental information and additional promotional days.
