Active around Lake Constance
Lake Constance is no place for couch potatoes. Much better than twiddling your thumbs: riding along the cycle paths around Lake Constance, paddling along the shore in a canoe or walking along well-maintained paths through the vineyards. For people who like to 'collect' mountain-tops, there is no shortage of them around Lake Constance. Alternatively, there is no better way to relax than floating gently along on an air bed.
Also, in winter you are never far from pistes with guaranteed snow and spectacular views into the valleys either while skiing or walking on snowshoes.
