Do they have a play set for kids to climb and play on? Swings, slide, etc.

Yes, it's to the side of the parking lot on the left at the top of the hill. ( The lot across the road from the pool.)

Don't remember seeing anything like that but it's a big park

Not sure. I just use the pool and lake.

Yes you should look them up on line

Yes and lots of other activities for kids, families, and adults.
