Sullivan County
Sullivan County
Sullivan County is in the Catskills region of southeastern New York, anchored by Monticello (county seat and largest village). The economy mixes Resorts World Catskills casino at Montreign / Monticello, the Bethel Woods Center for the Arts (Woodstock '69 site), agritourism, dairy farming, the historic Borscht Belt resort legacy, and growing NYC second-home demand along the Delaware River and Upper Delaware Scenic Byway. The County Clerk operates from 100 North Street.
