There is definitely (at least) 1 thing that the City of Henderson is good at: Parks. I've commented MANY times at how many awesome parks there are around, and O'Callaghan Park is no exception.
There are picnic tables that always seem to be in use. A large kids play area, tennis courts, a walking path and LOTS of grass.
I've been hesitant to review the park because it is a little hidden gem on my side of town and I don't really want anyone else to know about it! But trust me, if you are in the area or walking your dog, it's a great stop! You definitely don't feel like you are in the desert. Great job, Hendertucky!
