Here is an interesting (4-season) hike on the Appalachian Trail in New Jersey. It is a moderate hike (approximately 18 miles) with a few steep up and downs. Starting point is at the Buttermilk Falls Trailhead, Follow that trail to the AT, then head along the AT for about twelve miles to the Gren Anderson shelter (a good area to camp for the night). Break camp the following day, and continue along the AT for about 6 miles to Deckerton Turnpike. Hikers can expect a good amount of ridge walking with some exposure and also a few steep climbs. The NYNJ Trail Conference Maps 5 & 6 or 17 & 18 would be suitable for this trip. Plan on carrying 2 to 3 liters of water. Water is available at the campsite.
Make use of the outdoors; get out more.
