@littlelosttravel: Is this one of Scotland's most underrated castle ruins? Gylen Castle is found on the tiny island of Kerrera near Oban, and it's one of the easiest castle ruins to visit. It's free too! To get there, take the tiny ferry from Gallanach to Kerrera then walk about an hour. You'll soon reach the magical Gylen Castle. #scotlandtravel #kerrera #castlesofscotland #castle #scotlandexplore
