This glacial lake in the Yorkshire Dales National Park is England’s highest, at 377 m (1,237 ft) above sea level. It’s also one of only eight alkaline lakes in Europe. The stunning scenery holds plenty of interest for nature-lovers – managed by the National Trust, the estate holds a number of conservation designations, including being a Ramsar Site and a Site of Special Scientific Interest. A range of walks and hikes are graded for all abilities from easy to challenging – a popular one is to the waterfall at Janet’s Foss. Cycling trails are in development for all abilities and styles. Fishing is permitted - by boat only – for wild brown trout.
