Star Castle Hotel

Quick Take: Star Castle Hotel, St Mary's, Isles of Scilly

Rooms at Star Castle are finite by design — the hotel occupies a genuine Elizabethan star-shaped castle on St Mary's, the main island of the Isles of Scilly, and the number of rooms within the castle itself is strictly limited. If you want to stay inside the historic fortification rather than in one of the garden suites in the grounds, book early: those castle rooms go first, and the window for summer availability closes well before the season does.

The case for booking here is the location and the building itself. The Isles of Scilly sit roughly 28 miles southwest of Land's End, accessible only by helicopter or ferry, which means the island operates at a pace that most UK mainland hotels simply cannot replicate. Star Castle is the dominant accommodation landmark on St Mary's — a Scheduled Ancient Monument that has been operating as a hotel for decades. For guests who want the atmosphere of sleeping inside a historic fortification surrounded by Atlantic views, there is no comparable option on the island.

From a value-seeker's perspective, the room category decision matters here more than at a standard hotel. Castle rooms sit inside the original sixteenth-century walls and come with the spatial quirks , low ceilings, irregular layouts , that are part of the appeal. Garden suites in the grounds offer more modern proportions and are typically easier to secure. If you are travelling with children or prioritise space over character, the garden accommodation is the more practical choice and usually more accessible in terms of availability. If the castle rooms are gone, the garden option still gives you the grounds, the views, and the restaurant, so it is not a compromise that ruins the stay.

Getting to St Mary's requires planning regardless of where you stay. Both the Penzance ferry and the helicopter from Penzance involve advance booking, particularly during the summer months. Build that into your timeline: the hotel booking and the transport booking need to happen together.

If you want a Cornwall coastal alternative that is easier to reach, Carbis Bay Estate or Artist Residence Cornwall in Penzance are worth comparing.

Booking difficulty is low once you are on the island's radar , Star Castle does not have the reservation friction of a Michelin-circuit restaurant or a London hotel during peak season. The harder constraint is transport availability, not the hotel itself. Book both simultaneously and you will not have a problem.
