Cucamonga-Guasti Regional Park


Discover paradise right in San Bernardino at 800 N. Archibald Avenue. Located in the heart of Ontario, summer hours extend through much of September from 7:30 a.m. – 5 p.m. daily (and 7 p.m. on weekends). Right at the hub where business and culture align, this gorgeous park includes 150 sprawling acres within an otherwise urban space for fun, recreation and relaxation. With two lakes well stocked for fishing as well as a swimming complex with thrilling water slides, it’s the perfect place to cool off.

Enjoy zero depth water play parks and plenty of picnic tables and shelters throughout the park for your outdoor picnic adventure. Ideal for parties, corporate events, family reunions and weddings, the sheer size of the park and amenities can suit nearly any sized event.

Park ‘n’ Play

Water fun is one of the most popular reasons to head to this park, with year-round fishing specializing in trout and catfish. Boating via pedal boats, available to rent on summer weekends, are a romantic date option. With four large covered shelters for up to 300 people, with plenty of BBQ grills and smaller tables/shelters, the park is idyllic for your late summer shindig.

Swimming in the lagoons, ADA water slides or simply lounging in one of the cabanas for rent is a fabulous way to end the summer. What’s your plan for your park adventure?
