Leitisvatn or Sørvágsvatn as it is also called is the lake from which the waterfall Bøsdalafossur flows. The lake has an area of 3.6 square kilometres. This is the well-known lake that will create an optical illusion when seen from the cliff Trælanípan.
Leitisvatn is situated on the island Vágar. This is the island where your flight will descend and land if you come to the Faroe Islands by aeroplane as Vagar Airport is situated on the same island as Lake Leitisvatn.
