This disarmingly quaint town is almost too picture-perfect. “My teeth hurt, it’s so sweet,” one of our out-of-town guests joked as we crossed the covered bridge into the historic center. The blink-and-you’ll-miss-it 19th-century village is home to the stately Pitcher Inn, a classy general store, the meandering Mad River, and a cluster of perfectly maintained homes. It’s laid-back, dog-friendly, and peaceful. You could simply kick back and enjoy a glass of wine and chunks of local Vermont cheese in front of a warming fireplace, soaking up the mountain and river views. But you’d be missing out on some of the best four-season outdoor adventure in the East. Bring your gear; tiny Warren, flanked by the Green Mountains and a stone’s throw from both the Long and Catamount trails, is an outdoor lover’s paradise.
