Cucamonga-Guasti Regional Park

Great pond and small lake. Trout is the current fish. The park is nice and kept up pretty well and the playground is nice too. There is a HUGE eye sore of a little Waterpark that is laughable and dirty. Should tear it out, make it a bass pond and the revenue will pour in more over the water park/pool thing is bringing in from, what, 3 years ago. It's dirt. Bad, empty and just a waist....

Came here for a family reunion. I believe we had over 200 people and so many cars! The park handled the volume well. There are huge areas of shade thanks to the trees but the built in awnings with lots of tables under are great too! Restrooms were clean, park is clean, splash pad is great too.

We went for the Christmas lights. I have to say it's a large park we only experienced the evening with the Christmas lights so regional park staff had complimentary hot chocolate and coffee and a few crafts and coloring pages for kids which was so cool while adults finish their hot beverage. Not sure about during the day because I haven't gone but will revisit soon.

This place is a definite YES! It's $10 for parking as of 8/27/25. $15 for fishing per person. They sell duck food for $3. This place is a dreammmmm lots of shaded tables & grills. Several large lakes + a big park + splash pad. There's restrooms, a lil stinky but🤷‍♀️. I love that it's gated. There's security at the entrance & a security guy that drives around keeping the park tidy. There's no homeless or crackheads. It's an amazing place for families. There's sidewalks so stroller friendly. We made a day trip out of it. Grilling hotdogs, set up a tent, got reggae playing n the fishing rod n skates! Yeah, a dream(: ... Oh the pool is closed for whatever reason so there's no swimming areas.

This is a great place to take children. There is a playground with a great structure to climb on and slide down. But the main attraction is the splash pad. On a hot day there are several water sprayers to choose from or just run the pads from spray to spray. There is even an interactive sprayer that you can direct the spray. There is a big lake and a picnic area. It’s cost $8 to park (park entry). Great place to spend a day with children.
