Perched on the clifftops above Mawgan Porth, the Scarlet is an adults-only eco hotel like no other in Cornwall. All 37 rooms face the Atlantic, each with a balcony or terrace, and the hotel is built with serious sustainability credentials — unbleached organic robes, water-based paints, recycled slippers. The Ayurvedic spa is exceptional, with clifftop hot tubs, a natural reed pool, cedar sauna and lantern-lit treatment rooms. The restaurant serves a daily-changing seasonal menu using local and slow-grown ingredients. A complete switch-off from the world.
