Equipped with a pair of poles to help you along the path, Nordic Walking – deriving from Finland in the 1930s as a form of off-season training for skiiers – is a fun and accessible activity for all. Swinging your arms as you walk helps burn calories, while the poles reduce pressure on muscles and joints. bit.ly/2kFddkh

With the night to yourself, the countryside begins to play with your imagination – the forests, valleys and waves at one moment vivid and familiar, the next intriguing and strange. bit.ly/2lbCOBU
