Designed as an all-inclusive, ADA-accessible playground, Brendan's pairs its splash pad with ramped toddler sections and climbing nets so children of all abilities can play side by side. It is one of the metro's standout accessible play destinations.
When to go. Peak summer highs in O'Fallon average 89°F — warm enough for a splash pad through most of the season without being punishing at midday.
