Sun Retreats Birchwood Acres

In the foothills of New York's Catskill Mountains in Ulster County, Sun Retreats Birchwood Acres delivers a resort camping experience built around a private four-acre lake, an interactive water zone, two pools, and an activity calendar that runs from Memorial Day through Labor Day with barely a gap. Located at 85 Martinfeld Road in Greenfield Park—a small community in the rolling wooded landscape between the Hudson Valley and the Catskill high peaks—the resort sits within the reach of New York City weekenders and destination travelers alike, offering an amenity-rich alternative to the more rustic camping that defines much of the Catskill region. The result is a campground that functions as its own destination rather than just a base. Full hookup RV sites, tent camping, and deluxe two-bedroom cottages with full kitchens and screened porches accommodate the full spectrum of guest preferences. The four-acre lake with fishing docks and paddleboat rentals provides quiet water recreation, while the interactive Water Zone, outdoor swimming pool, and extensive sports facilities—tennis, basketball, volleyball, bocce, gaga ball, shuffleboard, handball, and human foosball—create an activity-dense environment particularly well suited for families with children. An arcade-inspired game room, laser tag, golf cart rentals, planned activities like arts and crafts and Bingo, and live entertainment throughout the season round out what is genuinely an impressive amenity lineup for a private campground. Greenfield Park occupies the transition zone between the Hudson Valley's softer topography and the more dramatic terrain of the Catskill Mountains to the west and north, where the glacially carved peaks rise to over 4,000 feet and define one of the most distinctive landscapes in the eastern United States. The surrounding Catskill Park encompasses more than 700,000 acres of state land with hundreds of miles of hiking trails, trout streams, and swimming holes. The resort's own wooded setting provides the natural backdrop—birches, oaks, and maples creating the canopy that gave the original campground its name. The Catskill region offers outdoor recreation at every level: day hikes to summit views on Slide Mountain and Hunter Mountain, Class III whitewater on the Esopus Creek, trout fishing in the legendary Willowemoc and Beaverkill rivers that define the American fly fishing tradition, and the summer stock theater of the Woodstock and Hudson Valley arts scenes. Kaaterskill Falls, one of the tallest waterfalls in the northeastern United States, is accessible via a popular day hike that showcases the Catskills' dramatic topography. The Hudson Valley wine country and the historic village of Woodstock add cultural dimensions to the outdoor recreation menu. Summer season at Sun Retreats Birchwood Acres runs May through September, with July and August at absolute peak capacity—reservations many weeks in advance are essential for summer weekends. The fall foliage season in October attracts a second wave of visitors who come specifically for the color show that the Catskills reliably deliver. Weekend rates at the resort reflect its popularity; midweek stays offer better value for flexible travelers. Book your site or cottage at Sun Retreats Birchwood Acres and let the Catskill foothills and the four-acre lake set the scene for a genuinely fun and activity-rich camping experience.
