    The Saint-Izaire Mill

    Mentioned as early as 1461, the Saint-Izaire mill was once used to grind wheat for the village inhabitants. A witness to the area’s rural past, it has endured through the centuries by adapting to the needs of each era.

    Today, this historic mill operates as a small hydroelectric power station, continuing its energy-producing role at the heart of the village.

    The Grey Heron

    The Grey Heron is the largest heron species found in Europe. It can easily be recognized by its grey and white plumage, its long S-shaped neck, and its long legs visible in flight. In winter, its bill turns yellow-orange and a small black crest appears on its head.

    Highly adaptable, it mainly feeds on fish but also catches small animals such as rodents. Grey Herons live as pairs during the breeding season and nest in colonies, often in trees. The young birds leave the nest after about 55 days.

    Village of Saint-Izaire

    Saint-Izaire is a fortified village whose history is closely linked to its episcopal castle, the former summer residence of the bishops of Vabres. Mentioned as early as 862, the village gradually surrounded itself with ramparts during the 12th century to protect its inhabitants from feudal conflicts.

    After the Wars of Religion, the fortifications lost their defensive role: openings were made in the walls, and some fortified gates were altered to allow carts to pass and houses to expand. Despite these changes, the layout of the streets, alleys, and houses has remained almost unchanged since the Middle Ages. The 15th- and 16th-century façades and windows still give the village its historic charm today.


Description

  1. Take the road towards Faveyrolles up to the first intersection, then fork to the right on a dirt road for 800 m (scenic view over the village). Reach the disused "Le Graudenc" farm building, carry on towards the culminating point at the foot of a high-voltage tower, then walk down the Gos creek valley and enjoy an extensive scenic view over the distant horizon.
  2. After a steep slope between two fields, fork to the left at the intersection right by the small stone cross. Walk past dilapidated buildings and follow the track down to the valley. On the valley bottom, right at the intersection, take a hairpin bend to the right above the sandpit which can be seen 50 m further.
  3. Walk along the shady bank of the Tarn river and through the hamlet of Les Alverhnes. After a 300 m section of tarmac road, go down to the left and pass under the stone bridge of the former railway.
  4. Go to the left of the tunnel along the Dourdou river and carry straight on, leaving to the left a nice private bridge over the Dourdou river next to the hamlet of Janolles. Follow the river and pass under another bridge of the former railway, then get back to the tarmac road.
  5. Take to the left towards the Mas de Gascuel. Walk along the farm and take the gently sloping dirt road that leads you back to the village of Saint-Izaire.

Recommandations

Box tree months are active from May to October. During the caterpillar phase, they feed on the leaves of box trees. They crawl down trees and move on long silken threads, although these threads are annoying when hiking they do not pose any health risk
