The playground is old but I am sure a lot of fun for kids. Built like a castle this is great for older kids wanting to play in a castle. The good thing is that there is a separate area for the smaller kids. In this way they do not get run over by the older ones. It has lots of musical instruments which should keep them interested for some time. St Edwards is going through lots of construction at the moment so parking could be an issue. If you do park remember to use your Discover Pass or pay $10 a time for parking.
This park has some amazing hiking and biking trails. Also great for dog walking. There is a good trail through the forest to the water. Getting back up is a little bit of an issue for me but is doable. Make sure you take water with you for the hike back up.
