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 river's 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.

• Visit one of the well-preserved period buildings in the village such as the general store, blacksmith shop, carpenter's shop, owner's house, foreman's house and a church.
