GR routes are long-distance hiking trails that traverse various landscapes, often connecting significant natural and cultural sites. The term "GR" stands for "Grande Randonnée," which is French for "great hike." These routes are well-marked and maintained, making them accessible for hikers of different skill levels. Typically, GR routes are part of a larger network of trails across Europe, particularly in countries like France, Spain, and Italy. Each route varies in length and difficulty, offering hikers the chance to experience diverse terrains, from mountains to forests, while enjoying the beauty of nature and local heritage.
