Allamuchy Mountain State Park Access provides entry to a 9,600-acre park system spanning Morris, Sussex, and Warren counties with over 36 miles of trails for hiking, biking, and horseback riding.

The park offers boat launches at Cranberry Lake and Jefferson Lake for paddling and fishing access, with a gravel parking area available at Deer Park Road for trail access.

Multiple day-use areas and facilities are available, though Allamuchy Mountain has very limited accessibility for people with disabilities.
