Need a bit of hygge? Head for The Saltbox in Kent. The gorgeous little modern cabin sits in the marshland in Elmley – the only National Nature Reserve in England in which you can spend the night! Feel at one with nature as you snuggle up inside and look out of the large glass wall, spotting cattle, rare hares and birds of prey, or head outside and take in the views while toasting marshmallows over the firebowl. It’s part of the Canopy & Stars Cosy Collection and stays start from £115 per night (sleeps two); canopyandstars.co.uk.
