Alpine Overlook. Exit 2, off of Palisades. The perfect beginning of a fall foliage hike. Flat surface for those that need it, more vertical trails for others.
Butterflies (Monarchs on their way south).
Hawks, black vultures (a swarm, or a vulture flight, more than 7, soaring above with their widespread finger tip wings), Long Island Sound visible across the Yonkers rise, Tappan Zee bridge being constructed north
---and a very good cheeseburger inside an overlook restaurant reminiscent of the Red Apple in the 1950s.
Need I mention: FREE!
See it on a Sunny Day.
