I was looking up information on medical spas the other day and found Buttermilk Spa in New York’s Hudson Valley. Now how cool was it that I found an eco-friendly medical spa? Because that’s what Buttermilk is. Not only do they use organic and natural products–obsessively organic, in their words–but they also use renewable energy. Solar and geothermal energy are toiling hard to heat the sauna, steam room, and mineral pool. The best part is you get to enjoy luxurious services and even have access to hiking trails, the nearby waterfalls, and the gardens of the Buttermilk Falls Inn, and even enjoy organic cuisine. Sounds like it’s got the ingredients of a perfect weekend getaway.
