The Delaware Valley Arts Alliance is a haven for the artists who flock to the hills and dales of Sullivan County.

This replica of a 1755 fort depicts the lives of European settlers who made their home in the Upper Delaware Valley. The settlement, called Cushetunk, was mostly farmers who had moved to the region in search of land. They formed the Delaware Company and purchased 10 miles of land along both sides of the river and built a fort for protection. This authentic reproduction of the wooden structure includes blockhouses, log cabins, an armory, herb gardens, and costumed guides who demonstrate what life was like here in the 18th century. Open weekends from Memorial Day through Labor Day.

Designed by and built under the supervision of John A. Roebling, the future engineer of the Brooklyn Bridge, the Delaware Aqueduct dates back to 1847 and is the oldest existing wire suspension bridge in the country. It once carried canal boats high over the Delaware River on the Delaware and Hudson Canal. It was so solidly built that when the National Park Service took over maintenance of the bridge in 1980, most of the existing ironwork was still in great shape. The Tollhouse, on the Minisink Ford side of the bridge, has exhibits and historic photographs, along with a reconstructed canal boat cabin. The D&H Towpath Trail is a 1-mile stroll along the 1828 towpath.
