Bac Lava: This beautiful Lakeland Tarn has lilies which should be avoided so as not to disturb them. There is only one obvious entry point, a steeply shelving stony beach by the Mosshause Gill inlet. In the summer the temperature is pleasant.
In the winter it is, naturally enough, freezing cold! The tarn is 1/2 mile west up the hill from Dobgill Car park at Thirlmere. There are paths on both sides of the Gill but stick to the track on the North side to avoid steep and slippery sections.
