Located within the picturesque salt pans of the Sečovlje Salina Nature Park, the Lepa Vida Thalasso Spa is definitely among Slovenia's most unique spa and wellness destinations. Constructed mainly of wood, the modern facilities blend seamlessly into the surroundings of the park, and offer incredible views of the landscape. Thalassotherapy is of course the medical use of seawater as a form of therapy ('thalassa' being Greek for 'sea'), and was first developed on the Brittany coast of France during the 19th century, and Lepa Vida offers various health the therapeutic treatments, including salt-pan mud baths, bathing in brine (the liquid that remains at the bottom of the evaporation ponds after hand harvesting), sea salt scrubs, full body massages, and much more. The spa can be accessed by either land or sea (for those with their own boats), and advanced booking is recommended.
