Western Massachusetts. I like the Pioneer Valley (Northampton, Amherst, Shelburne Falls, etc) but the Berkshires are nice too. Only about a 3.5 hour drive from central NJ, lots of good food, lots of breweries if that’s your jam. There’s decent hiking/outdoor activities and good antiquing. I also have to recommend The Book Mill in Montague (a used book store and cafe housed in an old grist mill).
