Decorte Park is a pleasant hike which is all flat...the first .5 miles is a well maintained the end of the boardwalk you can go either left or right...i recommend if you go left (towards the NJ Tpke 95) that you do not make the left at the end...very buggy and ends up at a dead end by the train tracks...furthermore, make a right at the end of the .5 mile boardwalk and you will encounter many other 'linked trails' going into the North Arlington area. My friend and I managed close to 4 miles among the 'linked paths' - Enjoy JB
