Castle Porth
Castle Porth is an anchorage tucked just below the dramatic Star Castle — a 16th-century star-shaped fortress that crowns the headland above Hugh Town. Drop the hook here and you're a short walk from the heart of St Mary's, the main island of the Isles of Scilly. The setting is hard to beat, with the old granite castle looming overhead and the sheltered waters of the sound stretching out around you.
