Fort Grey Shipwreck Museum, located in a Martello tower, offers a glimpse into Guernsey's maritime past with exhibits of artifacts recovered from shipwrecks around the island. Accessibility may be limited due to the historic nature of the tower, with narrow stairs and uneven surfaces. It's suitable for both solo exploration and guided tours, which may provide deeper insights into the collection. Opening times are seasonal, typically from April to October. A visit typically lasts 1-2 hours and has a small admission fee. Check the official website for current pricing and operating hours.
