A kilometre west of Midvágur, Route 40 meets the Shore of the Faroes's largest inland lake, bizzarely known by several names: Leitisvatn and Sørvágsvatn, though most local people simply call it Vatnid, literally 'the water'.
At the point where the road meets the lake shore you'll see a couple of boathouses and small huts sich were once used for storing peat. From here follow the bank southwards. The going can be pretty boggy in parts.
Near the cache the promontory, Trælanipa, falls precipitously into the sea from a height of 142m, parking the southernmost extent of the lake.
During Viking times slaves who were no longer capable of heavy labour were simply flung off the clifftop to their death on the rocks below.
Close by the cache you will see the Bøsdalafossur waterfall, which carries the lake into the ocean after flowing over an area of basalt rock at the waters southern point.
The path will lead you ca. 3km from start to cache.
