Sierre
Lake PramontLake Pramont was created from a former gravel pit that was flooded and landscaped to develop biodiversity. The lake is off-limits to visitors, but there is an observation post with an information panel where you can get a glimpse of the lake and, with a bit of luck, see some of the biotope's inhabitants: kingfishers, herons, beavers, frogs, snakes, dragonflies and butterflies.
