Europeans first settled in what was to become the Delaware Water Gap National Recreation Area in the 17th century. By the late 1800s, the Delaware Water Gap had become a popular vacation spot, attracting thousands to the palatial resorts in the mountains. The Delaware Water Gap National Recreation Area was originally created in 1965 to oversee activities centered around a reservoir that was to be the result of a dam to be built on the Delaware River at Tocks Island, although the project was ultimately defeated. Although several historical sites were lost, many survived and a few have been restored. Today the area is one of the country's most popular parks. Within its boundaries are rugged and beautiful wilderness, historic landmarks, and the wild and scenic Delaware River.
