Hiking and Biking
Bulls Island is a part of the D&R Canal State Park. The state park’s multi-use trail of crushed and packed stone provides more than 70 continuous miles of wide, flat pathway along the historic route of the D&R Canal and former rail lines. Numerous access points make it ideal for a day hike or bike trip in central New Jersey. The park’s trail system was designated a National Recreation Trail in 1992 and is a part of the East Coast Greenway, the longest hiking and biking route which connects Maine to Florida. Today, it is used by millions as a much-loved and needed recreation corridor in Central New Jersey.

Loop Trails
A 30-mile-long stretch of parallel paths connected by six bridges over the Delaware River creates multiple loop trails linking New Jersey’s Delaware & Raritan Canal State Park with Pennsylvania’s Delaware Canal State Park. Along these routes, there are numerous recreational opportunities as well as river towns with rich histories, eateries and shops. The loop trails offers beautiful scenic views and the natural landscapes of the Delaware River Valley.
