"Nestled in Pennslyvania’s Pocono Mountains (about three hours from New York City), the Lodge at Woodloch is the adults-only sister property of the family-friendly Woodloch Pines Resort, about two miles down the road. The kid-free spa resort has 58 accommodations (each complete with a private balcony), over 35 classes (from silk scarf painting and smoothie demos to evening kayaking and axe throwing), and six-plus miles of trails (ideal for hiking and forest bathing). Guests also enjoy three gourmet meals per day (plus snacks)—many of which use herbs and produce grown on-site or locally (think: handcrafted black bean burgers served with garden greens, pasta with summer squash)—as well as the use of indoor and outdoor swimming pools (the latter overlooks the surrounding forest), whirlpools, saunas, and a 3,000-square-foot fitness studio." - Lauren Dana Ellman
