Royal Champagne Hotel & Spa 9 Rue de la République, Hameau de Bellevue, 51160 Champillon, France

As this retreat takes a holistic approach to relaxing and rebooting, a cocoon-like spa was built and it measures more than 15,000 square feet at the foot of the vineyards. Its curved wood exterior reveals a spa with an intimate atmosphere that is as unfussy as it is indulgent. With 9 treatment rooms including 2 couples suites, there is always time and space for pure pampering. For complete relaxation, there are two swimming pools among its many amenities. The 25-meter-long indoor pool is bathed in light and adjacent to a Jacuzzi; the outdoor pool (16 meters long) is surrounded by clusters of grapes.
