La chute du feuillage #2 - The Harriman State Park -

You should go to see such a marvelous fall folliage even after Nor'easter in the end of October or otherwise -- Harriman State Park is the second largest state park, following the Adirondacks, in New York. Located in Rockland and Orange counties 30 miles (48 km) north of New York City, it is a haven for hikers with over 200 miles (320 km) of hiking trails.

It' just 30-40 minutes drive from Manhattan and one of my friends, she lives here for 28 years, hikes the trails once a week, which is awesome!
