The spa in Cransac, made from acacia wood, and sitting above the town on “la montagne qui brule” is surrounded by the largest acacia forest in Europe. If you visit “La forêt de la Vaysse” in May the air is full of the smell of acacia blossom (a glorious mixture of the smell of honey and jasmine) and the sound of the bees working away on the early summer treat acacia honey. Go on a Saturday and you can also treat yourself to some acacia fritters or buy a bottle of the syrup at the local market.
The thermal springs, that have been know since antiquity, became famous throughout France in the 17th century and people still come to take the water, a “cure” can legitimately be prescribed by your doctor. The “curists” are a much sort after section of the tourist market. Walking through the forest you sometimes see the pipes weaving through the trees taking the precious waters to the spa and even the ground steaming as the mountain “burns”.
