Primitive camping is allowed. Campsites must be at least 150 feet away from the nearest road, trail, or body of water. Camping for more than three nights or in groups of ten or more requires a permit from a Forest Ranger. More details here: https://www.dec.ny.gov/outdoor/41282.html
Primitive camping is allowed on many DEC lands, including Forest Preserve lands in the Catskills and Adirondacks, as well as on State Forest lands outside the Preserve. Primitive camping is prohibited on Unique Areas, Wildlife Management Areas, and a few other categories of state land.
Where to Set Up Camp
The best place to camp is at designated primitive tent sites. These sites are typically flatter than other areas and have deeper, harder soils more resistant to heavy use and erosion, minimizing the impacts of camping. Many sites have nearby pit privies and rock fire rings.

Campers are encouraged to use designated tent sites. They are often close to trails and provide views of ponds, lakes, streams or rivers. These can be a source of water when properly treated.
All designated primitive tent sites have yellow and black "Camp Here" markers. Many sites on lakes and ponds are identified by a yellow number against a dark brown wooden plaque typically attached to a tree near the water's edge.
