The Nest Collective, which stages folk music events in green spaces, is running six nature walks along chalk streams in southern England in June. Each walk is led by the collective’s founder, Sam Lee, who is a Mercury prize-nominated folk singer, and an “eco pioneer” special guest. For example, the walk along the Rivers Cray, Darent and Thames is with biologist Dr Amy-Jane Beer. The other locations are along the Chess, Stour, Colne, Kennet, Mimram and Beane; all start and end at a railway station a short distance from London. The three- to five-mile meanders include several stops for songs and talks. The collective is also taking walkers and singers on a turtle dove pilgrimage in Sussex (10-13 June) and a salmon pilgrimage in the Cairngorms (17-20 June).
