The best fall views can be found at the top of Elk Mountain, which is taller than anything else in several counties. Climb up the black-diamond Seneca Trail for a serious workout, or take the gentler Lenape Trail for an easier climb. (Elk Mountain Ski Resort runs its chairlift during its fall festival, October 13 and 14.) For the less ambitious, drive to Ridge Road in tiny Ararat, park near the Methodist church, and follow the road on foot—the views go on forever.
The real inside scoop, however, is that Susquehanna County, the part of the Endless Mountains closest to New York, offers the last budget real estate within 150 miles of the city. Astrid Glodek of Country Landmarks (570-222-8000) has a good track record for finding second homes or building sites for the New York crowd.
