Runaz - Milliery - Baulin

One of the most demanding trails in the Valdigne purely in terms of elevation gain, this 6.9-kilometre route climbs from Runaz at 839 metres to the high-altitude pasture of Baulin at 1865 metres, gaining over 1130 metres. The path passes through Milliery, a traditional Aosta Valley hamlet with notable rural architecture — stone barns, wine presses, and ancient storage buildings of ethnographic interest. Beyond the village, the trail enters wilder terrain, moving through mixed woodland before reaching open mountain pastures. The reward is sweeping views of Mont Blanc and the peaks of the Valdigne. Baulin remains an active summer alp where livestock and shepherds continue a centuries-old pastoral tradition.
