Doo Lough - County Mayo
Doo Lough (Black Lake) is one of the deepest lakes in Ireland and surrounded by steep mountains. It is a lake for which the adjective “awesome” is entirely appropriate. Some would add “forbidding”, while others might say “majestic”. It lies at the foot of the Sheeffry Hills to the east and the Mweelrea Mountains to the west. In fact, Mweelrea rises so steeply that it casts a shadow across the lough from early afternoon .
