Julia Bradbury and Matt Baker head off on a trip through the New Forest, to celebrate the height of Spring. After catching their lunch in the seas off the Hampshire coast, Julia spends the night under the stars in a geodome - the last word in camping chic. The next morning, she and Matt discover how to record the Spring dawn chorus for posterity. Meanwhile, John Craven finds out what truly seasonal food is available in Spring, and Katie Knapman goes star spotting in the UK's only Dark Skies Park.
