Was at Half Moon about 4 years ago, and have a 4 night stay this Aug. reserved. Here are some pics from our last visit.
Half Moon State Park. Nice remote park. Good sized sites if you know which to reserve. The waterfront ones reserve first. I might be able to help if your looking at certain sites there is I have a database of good sites there.
We'll also be doing Jamaica State Park too. Have been to Gifford Woods, Lake St. Catherine and Smuggler Notch State Park in that state.
