Il Prarayer is an alpine plateau located at about 2000 meters above sea level, at the end of the Place-Moulin lake. It is reached by a simple path that runs along the lake, almost always flat. The environment is open, with meadows, small streams, and some alpine pasture buildings. The landscape is surrounded by high peaks and glacial environments, clearly visible in the background. The Rifugio Prarayer is located here, used as a base for longer excursions. The area is suitable for a quiet break after the walk along the lake. Itineraries to side valleys and high-altitude routes start from here. Despite the altitude, the setting remains accessible and not very demanding.

The Place Moulin dam is a majestic arch-gravity dam, designed to make the most of the narrow and incised conformation of the valley. Its concrete structure develops with a slight curvature, which allows the water's thrust to be transferred to the lateral rock walls, reducing direct pressure on the base and ensuring high stability. With a height of approximately 155 meters and a crest length of over 600 meters, it represents one of the most imposing hydraulic works in the Italian Alps. The artificial basin formed upstream reaches a capacity of over 100 million cubic meters of water, mainly fed by the Buthier stream and glacial meltwater. The plant is an integral part of a hydroelectric system: the accumulated water is conveyed through penstocks to power plants located downstream, where the head is transformed into energy. The management of levels is regulated by surface and bottom outlets, designed to control both floods and ordinary releases.

The Marmitta dei Giganti in Bionaz is a striking cavity carved into the rock that tells of the power of the alpine glaciers. It formed during the last ice age, when meltwaters, laden with sand and stones, channeled into powerful vortices: the debris, rotating ceaselessly, smoothed the rock to create this deep, almost perfectly shaped "pot". Alongside the scientific explanation, the charm of legend also survives: it is said that giants dug these cavities, using them as containers or leaving their superhuman strength imprinted on them. It is precisely this intertwining of nature and imagination that makes the place so fascinating.
