La glacière Travel Guide

La Glacière, nestled in the Straiture Valley within the commune of Ban-sur-Meurthe-Clefcy, is a fascinating natural attraction in the Vosges Mountains. The Straiture Valley itself is a protected Natura 2000 area known for its biodiversity and peaceful environment. La Glacière is a specific site within this valley, characterized by a granite scree where, according to local lore, ice can persist beneath the stones even during the warm summer months.This phenomenon is due to the unique geological conditions of the area. The accumulation of granite rocks creates a natural cooling effect, trapping cold air and preventing it from escaping. Mosses found on the stones also contribute to the phenomenon, as they can absorb up to 40 times their weight in water. While the presence of actual ice may vary depending on the season and weather conditions, the area consistently maintains a noticeably cooler temperature, offering a refreshing respite, especially during hot days.Historically, places like La Glacière were essential before the invention of refrigeration. Natural ice cellars provided a means to preserve food and drinks, making them valuable resources for local communities. The surrounding Straiture Defile adds to the area's appeal, featuring a narrow passage carved by the Petite Meurthe river between mountains. The landscape is marked by forests of beech and fir trees, creating a mysterious atmosphere. Today, La Glacière is a popular spot for nature lovers, hikers, and those seeking a unique natural experience in the Vosges.
