"Topnotch Resort, up on Stowe's mountainside, is a retreat for all seasons. At the mod 68-room ski lodge (there are an additional 23 rental homes you can reserve on site), you can sweat it out at the spa after an epic ski session during the winter, and take out your day-to-day stress on one of six outdoor tennis courts come summer. Tack on horseback riding in autumn, just as the leaves are changing shades, and hiking and biking in the spring—plus a dog-friendly room policy and outdoor meals overlooking the mountains—and we're sold."
