The deal has been the same since 2020: a solar-powered timber cabin within reach of a city, your phone in a lockbox, an emergency Nokia in case the world really does need you. These two are the first on the coast. Barclay is a steep drive and then a walk uphill; Wilfred comes through Exmoor and over the UK’s steepest A-road. Both look at the Celtic Sea. Log burner, instant camera, three nights minimum, from £540.
