Peat bogs

Finistère has over 200 peat bogs known locally as 'tourbières'. Our natural heritage is exceptionally rich and varied, but the area around the Monts d’Arrée and the Montagnes Noires abounds in peat bogs.

Peat is a fossil fuel created when two elements decompose together: organic matter and water. According to the water levels of a particular site, a peat bog can become a valley, a slope, a spongy surface or even a hillock.

  • Tourbière du Mougau – Commana in the Monts d’Arrée
    What to do: the walk with information boards of la tourbière.
    What to see: the megalithic alley of Mougau, the Roc'h Trévézel...
  • Tourbière de Langazel – Trémaouezan
