You can take time to visit Angry Orchard during your travels to Walden. Make some time to visit the shops while you're in the area.
You can spend an afternoon studying the exhibits at Orange County Farmers Museum during your trip to Walden. While in this family-friendly area, you can savor the top-notch restaurants.
Walden is small, and you are probably visiting for the Angry Orchard. My wife and I love the chance to go visit small towns and slow down a bit, and Walden provides that with good restaurants, friendly faces and plenty of outdoor space.
Be sure to visit Angry Orchard in Walden for their cider tastings and tour. New Paltz is a bit of a drive, but worth it if you're after antiques/the art scene (it has the same feel as New Hope, PA).
Not a lot to do here but lots close by. Tin Brook is nice.
