November has obliged, and today is a beautiful day for a New York City hike!
The NYC Department of Parks & Recreation website offers a great list of trails in the Bronx, Brooklyn or Queens.
If you're in Manhattan, and you're not interested in leaving the island, check out this site with quiet walks in Central Park. Don't be alarmed by the horrible website design. The suggested hikes are great, and the poetic descriptions may inspire your inner Thoreau.
