Dennis and Jan Kelsall published their first Cicerone title in 1995 and have since written around 35 guides to some of Britain's most popular walking areas: they have also become regular contributors to various outdoor magazines. Their enjoyment of the countryside extends far beyond a love of fresh air, open spaces and scenery: over the years Dennis and Jan have developed wider interests in the environment, geology and wildlife, as well as an enthusiasm for local history, which so often provides clues to interpreting the landscape.
