Cragside - Nelly’s Moss lakes walk - (NT) - "Enjoy a family-friendly flat walk around two of Cragside’s historic lakes, created by Lord Armstrong in Victorian times to supply water and power to the house and gardens. Look out for frogs and toads crossing your path and even herons dipping their feet in the water. There's an alternative route for buggies and pushchairs too." - from the National Trust website
