The category has grown substantially since 2020 — the rise of long-weekend domestic travel and the move toward dog-friendly couple breaks have created real depth at this size. The best stock is in converted fisherman's cottages (Mousehole, Polperro, Port Isaac), wooded estate properties (Helford, Lanteglos, Penrose), and modernist boat-house conversions (Fowey, Falmouth, Carbis Bay). The middle of the market — generic two-bed cottages with no specific identity — is to be avoided; the experience is closer to a hotel room with a kitchen than a proper stay.
Cornwall's south coast suits couples better than the north for most of the year — calmer weather, more wooded landscape, more atmospheric estuary settings. The north coast does autumn and winter exceptionally well, when the storms and the empty beaches become the point. Spring stays in Cornish gardens (Trebah, Glendurgan, Heligan, Caerhays) are a strong reason to book the south; autumn stays around Tintagel and Boscastle are a strong reason to book the north.
