After a stressful autumn, darkness and unfortunately lots of rain (where is the snow?) what can be better than aday or even a weekend at a spa? To make it even better, an eco-spa! The best thing is that it is totally justified that you go together, it's simply an awesome present. Good for both body and soul.
A google search for eco spa will come up with loads of alternatives, but this site will give you a lot of places in Sweden to visit: Organic Portal
