Cucamonga-Guasti Regional Park

$5 per person/ $1 per dog

As the dog days of summer come to an end and the regular summer swim season closes, San Bernardino County Parks hosts its annual Doggie Pool-ooza event at Cucamonga-Guasti Regional Park in Ontario. During this event owners can bring their four legged pals who have had to endure the summer heat in a fur coat, for a last dip in the cool pool. In addition to the zero entry pool the event also boasts a Doggie Swimsuit Competition, a Dog/Owner look-a-like contest, Top Dog Talent Show, and Lil’ Dog Races.
