Allaire State Park offers access to the Manasquan River for fishing and paddling activities, with seasonal canoe rentals available through private vendors.

The park features multiple parking areas including a large gravel lot on Hospital Road for the southern trail section, and fishing access points along the Manasquan River at various locations including Hospital Road and Squankum Yellowbrook Road.

Annual trout stocking ensures good freshwater fishing opportunities, though a New Jersey fishing license is required.
