Moss Dub is a natural pool (tarn) in the Ennerdale Valley, located south of the River Liza in the Ennerdale Forest. Moss Dub is surrounded by rhododendrons and coniferous woodland, it is a small, shallow tarn. The tarn is thought to be a remnant of a former great lake. Access to the tarn is from the head of Ennerdale Water via forest trails.
Due to the tightly packed woodland around the tarn, clear views are difficult. The best angle is from the west, looking along the outflow which takes in a few interesting twists and turns.
If you visit the tarn, watch out for the docile Galloway cattle which are allowed to roam free in the valley – please keep all dogs on leads in the vicinity of the cattle.
If you’re lucky, you might see Roe deer which inhabit the forest – the best time to spot them is either at dawn and dusk. Red Squirrels may also be sighted, especially around the Gillerthwaite area.
The forest is also home to a variety of birds including Peregrine falcon, Raven, Buzzard, Kestrel and Heron.
