Troutsdale was my first experience of cycling locally, when I first came to live in Scarborough. The memories remain after almost 60 years! Troutsdale is a treasure lying roughly south-west of Langdale End. Both Troutsdale and Rosekirk Dale Fens were given the status of Site of Special Scientific Interest in 1984. These two fen systems lie in the narrow upper reaches of Troutsdale and show examples of spring and flush fen flora in the local area where springs emanate from the Corallian Limestone. Such fen systems are restricted to areas in Norfolk, Oxfordshire, Anglesey and the North York Moors, therefore they are nationally rare.
