Glehn's Castle, located in Nõmme, Tallinn, offers a unique visitor experience primarily focused on its surrounding, free-to-access park rather than regular interior tours, as the castle building typically hosts private events or serves as a student union. The expansive park is freely accessible year-round, best enjoyed from spring to autumn, and is perfect for solo exploration, featuring distinctive statues like Kalevipoeg and the 'Crocodile.' While the park is free, any rare access to the castle's interior for specific events might incur an admission fee, and general guided tours are not available. A typical visit to explore the park and admire the castle's exterior usually lasts 1-2 hours. The location is easily accessible by public transport from central Tallinn, making it a charming, unconventional historical site perfect for leisurely walks and appreciating unique architecture and nature.
