Trakai, the ancient capital of the Grand Duchy of Lithuania, is nestled amidst picturesque lakes. It is best known for its captivating 14" century fairytale castle on an island on lake Galve, now housing a museum. Other than exploring the Gothic red bock castle, the town of Trakai itself with its quaint architecture is well-worth wandering around. There also are plenty of options for fun on the placid waters of the surrounding lakes. Due to its proximity to Vilnius, Trakai is a popular day trip destination.
