A breath-taking journey through the Gleniff Horseshoe, a valley between the Truskmore and Kings Mountains, begins near the town of Grange in the County of Sligo. The unusually shaped Benbulben Mountain, which is regarded as the emblem of County Sligo around the world, is located at the base of the Dartry Mountain range, which includes Grange. Benbulben Mountain, which was formed by glaciers during the Ice Age, is home to a rich variety of flora and wildlife, including several species that are unique to its slopes in Ireland. A variety of stores, bars, and restaurants can be found in the county town of Sligo, which is just 10 miles away. Due to the quantity of shells in the waters surrounding the town, its name is derived from the Gaelic word Sligeach, which means Shelly River.
