According to the DEC’s 2020 Campground & Day Use Area Schedule, all state campgrounds will remain closed until at least June 1.
”To reduce potential community spread of COVID-19, all campgrounds, and pavilions are closed to overnight visitation through May 31. All visitors with reservations will be issued a full refund. New York State has suspended all new camping, cabin and cottage reservations for the 2020 season until further notice. If you’ve made a reservation for the season beginning June 1, and we determine your campground is safe to open, your reservation will be honored. However, visitors who wish to cancel an existing reservation may do so and receive a full refund.“
This includes state campgrounds like Kenneth L. Wilson. The campgrounds themselves remain open for day use, i.e. you can walk the public grounds. However, public facilities are closed and unstaffed, and no fees are charged. Overnight camping is not allowed.
This does not affect hiking in the Catskills, which NY State still considers and healthy and positive activity if you #RecreateLocal and take common sense precautions.
