Wildlife, Camping Alert: To reduce the risk of attracting black bears, campers should never leave food, coolers, or backpacks unattended, especially when sleeping. Food preparation and cooking should be undertaken away from where people sleep. When finished, all food should be secured and waste taken to proper receptacles. Bears have a very good sense of smell, so food and other items with a strong scent, like toothpaste and deodorant, should not be stored in tents. Should a bear approach you, make loud noises and slowly back away. Do not run. Never get between cubs and an adult bear. All bear encounters should be reported to the Park Police at (845) 786-2781. For more information on how to store you food and preventing bear conflicts see DEC's website on Reducing Human-Bear Conflicts

Lake Tiorati was formed by clearing swampland in Harriman State Park and constructing a concrete dam to make two ponds into one large lake. Surrounded by meadows and rolling, wooded hills, the park offers excellent swimming, fishing, boating and picnicking. In winter, if conditions allow, the lake is used for ice fishing. The pioneer campsites near the lake may be used by bonafide groups.

Scout camping is available.

Fishing - NYS fishing license required.
