It’s right by the busy street but the kids still had fun!

A nice park with lots of variety. There are 2 play gyms for kids of all ages.

This park is very nice for kids they have nice little kids slides too

Not a very big park, but it has swings and a fun climbing structure.

Google says dogs can enter but when we arrived it said no dogs allowed
