Nicest hike in the area, HOWEVER the parking @ State Line Trail is problematic weekends and during the nice weather, as you are parking at a marina and subsequently have to compete with boaters who are also looking to park their cars. A better way up is to begin in Warwick NY at Cascade Lake Park. Follow the blue markers up to the AT, that gives you the additional advantage of another view at Prospect Rock- and plenty of parking available. The trail up is not as much of a grind either. The only disadvantage is this route isn't accessible via mass-transit, as the State Line Trail has NJ Transit buses 196/197 near the trail head.
