Just because a beach is in the middle of a conurbation doesn't mean it's not wild. Anna, Ellie and I set off for Armchair Cove in Paignton, which you can get to via a suburban street and a short walk past a holiday camp and under the railway line. You emerge into a green and blue heaven, a grassy cliff top with the sea spread out in front of you like a magic blue carpet. Armchair Cove is tucked away under the cliff, a small oasis of calm fringed with exotic, Gaudi-esque rock formations. The water was very clear for the time of year, and warm, at 14.7, and we swam around, heads permanently down, marvelling at the beautifully coloured seaweeds and intricately twisted rocks. Then there was a shout. "Green anemones" cried Anna, and there they were, snakelocks anemones rippling in the water, green ones and pink ones, surrounded by a kaleidoscope of pinks, purples, browns and greens.
