Deer Trail Park in Watertown is a neighborhood park in the middle of a subdivision.
There are two play sets (one larger, one smaller), along with a couple of more unique features, such as this ball maze.
It definitely was entertaining for my little guy, but this park struck me as a lot of fun for older kids. There were quite a few different climbing apparatuses.
This park also has a very ample lawn area.
If you're lucky enough to be there on the right day, you may even get the bonus entertainment of watching a TRUCK come and pump out the port-a-potty! Highlight of the trip for my toddler:)
Obviously, there is a port-a-potty onsite.
