Set within 125 acres of Cornish coastline, with its own stretch of white-sand Blue Flag beach, the heated 20-metre infinity pool at Carbis Bay is hard to beat. With pinch-me views over St Ives Bay, you quickly understand why it is often voted one of the most beautiful beaches in the world. Throw in the palm-dotted subtropical garden and, when the sun shines, you’d be forgiven for thinking you’re in the Med. Done dipping? Retreat to the tiled sun deck to soak in yet more of those ocean views; keep your eyes peeled for dolphins and seals who occasionally frolic in the bay.
