Hebridean Island Cruises’ charming boutique vessel carries just 48 guests around the Western Isles of Scotland on all-inclusive cruises lasting four to nine nights. (It has the distinction of being chartered twice by the late Queen Elizabeth II for private vacations to celebrate her birthday with other members of the British royal family.) The ship’s interiors resemble a Highland lodge and are decorated with comfy sofas, framed watercolors, and nautical clocks. There’s also a delightful conservatory and a well-stocked library. Hebridean Princess is unique in the world of cruising (although she was joined by Hebridean’s 38-guest Lord of the Highlands in 2021) and offers a relaxing yet invigorating way of experiencing Scotland’s untamed natural beauty.
