Allaire State Park is probably best known for its historic 19th-century ironmaking town, Allaire Village, and its antique steam trains on the Pine Creek Railroad. The Manasquan River, which winds through the park, attracts canoeists and fishermen. The rivers floodplain provides habitat for over 200 species of wildflowers, trees and plants as well as habitat for birds and other wildlife. Hikers, mountain bikers and horseback riders enjoy the many trails in the park. Camping facilities include 55 tent and trailer sites, six group sites (holding a total of 300 campers) and two yurts (each sleeping up to four).
The park is located in east central New Jersey, south of I-195 and west of the Golden State Parkway.
