Less than three kilometers (1.6 miles) north of Oban, Dunollie Castle sits on a hilltop overlooking the town. It’s just a 15-minute walk from town along a trail through woodlands to reach the castle, where you can tour the ruins. While a castle has stood here since the 7th century, the ruins that visitors see today date largely from the 15th century. The adjacent museum covers the history of the Clan MacDougall, which has been based here for some 900 years—the clan continues to meet at the castle periodically, with members traveling from around the world. (The next gathering will take place in 2019.) You can pick up items incorporating the MacDougall tartan at the gift shop, and leave time for tea and cake at the on-site café.
