A mountain pond is a rarity in itself in the Aosta Valley, where standing water is scarce. The Holay pond lies between 750 and 790 metres above Pont-Saint-Martin, and it keeps relict species of plants and animals that have almost disappeared from the rest of the region.
What to see
The reserve really is small: 1.45 hectares, established in 1993 along with other protected areas in the valley. In 2005 a special conservation area was recognised around the wetland, covering a wider surface and joining the European Natura 2000 network. The pond sits a few steps from the ruins of the castle of Suzey, on the same promontory.
Our editors' tip
This is a stop, not an outing: half an hour is enough, and it makes sense alongside the castle and the walk above Ivéry. Spring is the moment, when the pond vegetation is at work and the amphibians make themselves heard.
