Ossian's Cave in Glen Coe is a mysterious spot tucked away on the Aonach Dubh ridge of the Three Sisters mountains. Legend has it that this natural cave was the birthplace of Ossian, son of Fionn Mac Cumhaill and Sadbh. The cave is hard to reach, with a steep climb known as "Ossian's Ladder" leading to its sloping interior. Despite its treacherous allure, the cave offers stunning views and a connection to ancient Celtic folklore.
