As a Biosphere Reserve, Boel Valley is one of the most significant and representative places in France. A wooded valley beside the sea, where you can see the best places in Brittany in the middle of a green and flowery valley. When it seems that you've left the forest, you enter a steep area with little vegetation here and there, leading to a steep cliff that stretches for miles. They say all the magical places are difficult to access. This place is no exception. For years only a stone bridge has linked this region with the rest of the country, crossing the river Boel.
