Salt Cave Therapy Vermont Salt Cave Spa & Halotherapy Center is a contemporary wellness center built around a man-made salt cave composed entirely from Polish rock salt and located in the foothills of Jay Peak in Northern Vermont. Only 10 minutes from Jay Peak Resort and 40 minutes from St. Albans, the Vermont Salt Cave Spa offers 45 minute salt therapy sessions for total relaxation. Participants enjoy the well documented health benefits of Salt Therapy, popular in Europe since the first salt cave spa opened in Poland in 1838 but only now starting to gain popularity in the US. The cave-like interior of our salt chamber or grotto is essentially a cave micro-climate and was created keeping it as natural as possible to ensure maximum health benefits. The halotherapy machine is imported from Poland, the home of modern salt therapy and is in fact rated as a medical machine. It takes pharmaceutical grade sodium chloride and crushes it into miniscule particles that is released in specific, controlled quantities into the air for dry salt therapy.
