This week on Countrywise Guide to Britain we continue our tour of the spectacular countryside - inspiring us all to pull on our wellies pack a picnic and get out and explore the great outdoors this weekend.In this episode Ben Fogle gets very close to nature as he takes a chilly naked dip in one of Snowdonia's hidden lakes; Liz Bonnin is in Galloway in Scotland and its Dark Skies Park with a group of inner city kids - to inspire them with a nocturnal safari and the magic of the stars; and we are in a remote corner of the Yorkshire Dales to meet Shepherdess Amanda Owen and her family as they welcome baby number 9 into the flock.
