Castle Stalker, a picturesque four-story tower house, is set on a tidal islet on Loch Laich near Appin. While the castle itself is not always open to the public, guided tours are available at select times and must be booked in advance; visits are restricted, so checking availability beforehand is essential. The castle's remote location means accessibility can be challenging, and reaching the islet may involve navigating uneven terrain. It's generally suitable for both solo travelers and guided groups, offering photographic opportunities and historical insights. The cost for a guided tour is approximately £10-£20. A typical visit, including the tour and enjoying the surrounding scenery, usually lasts around 1-2 hours. Keep in mind that access might be limited due to weather conditions or private events.
