Huge and well maintained park. Also known as "The Butterfly" or "Dinosaur" park by the locals, depending on which side of the hill you plan to visit. I prefer the Dinosaur side. : ) Close to the 95 and right across the way from the library and YMCA so it's super convenient if you have little ones in preschool. It's basically play-date central.
Great playground with slides, swings, and splash pad for the kiddos. Trails for the adults and plenty of room for your four legged friends too. Also a dog park at the north end of the park. It's not the best dog park I've seen but it's decent. Volleyball courts, BBQ grills with covered seating, an amphitheater and awesome views of the mountains. My kids and I really like it here.
