Wildcat Blvd. & Whitney Ranch Parkway in Rocklin, CA.
Off the I-65.Blue Oaks exit. Turn east. Turn left on Sunset. Right on W. Stanford Ranch Rd. Left on Wildcat. Right on Whitney Ranch Pkwy. Make a U-Turn where you can, after you see the park.
This is a fun park, kind of out of the way, but not very crowded so it is worth the drive. It has fun water features that dump and spray! The playground is HUGE! This is the biggest and tallest playground I have ever seen at a park. The big kid playground is three stories in some spots. The slides come down from that high. It has lots of paths around and plenty of things to walk on and run around. It has a cute small kid playground with horses to ride, swings, and plenty to climb on and slide down. It has many benches that are covered and you can reserve the BBQ areas as well. Fun for all ages.
