Cucamonga-Guasti Regional Park

Ontario City has become one of the most popular residential areas thanks to its strategic location near downtown Los Angeles and San Bernardino County. As such, the city offers a wide range of family-friendly activities and attractions in the form of lakes, recreational centers, museums, cultural events and festivals, and parks. And speaking of parks, Ontario takes pride in being home to the famous Cucamonga-Guasti Regional Park, a giant 150-acre park offering a plethora of fun activities and attractions for the whole family. The park is a perfect getaway destination especially during the summer season. Below are some of the top features and activities that you can expect when visiting the spectacular Cucamonga-Guasti Regional Park in Ontario:

Waters based activities.

For starters, the lake is home to two major freshwater lakes.  Both lakes serve as designated fishing areas for fishing enthusiasts. The lakes are fed with a fresh supply of fingerlings every few months in order to maintain a constant fish population within the lake at all times. Fish types available in the lake include bass, catfish, and trout. For those who are not into fishing and swimming, the park offers aqua-cycle, kayaks, and pedal-boats on a rental basis. There is also a state-of-the-art swimming complex featuring a giant swimming pool, a modern waterpark, and water slides. These features make the park a perfect place to cool off during the summer.


Cucamonga-Guasti Regional Park offers picturesque picnic locations for families and romantic couples. Picnic shelters, tables, and benches are available through the park and barbecuing is allowed within the park. It is a perfect way of spending your free time with your loved in a relaxing environment away from the congested streets of the city. Some of the picnic shelters are large enough to accommodate corporate events, large parties, and reunions.


The park has plenty of open play areas and ball diamonds where both adults and kids can play and compete in different sports. There is also plenty of space to stretch and walk around for those who want to stay fit.

Other features

Although Cucamonga-Guasti Regional Park is not outfitted with any sort of camping facilities, there are several guest lounges where visitors can spend a night or two during their visit to the city. Parking and restrooms are available and well maintained. It is worth noting that the park charges a few dollars for one to access some of their facilities for maintenance reasons.
