| Why you should go: To look out over "beautiful landscaped sub-tropical gardens" and take in "spectacular" sea views (The AA) from an 18th-century castle. Tregenna Castle sits within 72 acres of private grounds and is around 20 minutes' walk from the centre of St Ives. The hotel has welcomed its fair share of celebrities and dignitaries, including David Bowie, Sir David Attenborough, Dame Judi Dench, and the world leaders during the 47th G7 Summit in 2021. What's the big deal? We've negotiated savings of up to 35% for Travelzoo members. Two nights' accommodation in a Castle Double Room, with breakfast, £30-per-person dining credit, a round of golf, and 10% off treatments at Castle Beauty, is now £189. |
