Only eleven people are known to have reached the top

Near Sandavágur village, on Vágar island, there is an outlook from which you can see Trøllkonufingur, the Witch’s Finger. It is a free standing rock, although it is hard to see from the outlook that the rock is separate from the rest of the cliff. There is a path that you can walk so you can see this cliff better. 

Take a screenshot of google maps zoomed in the village and you'll find the path. It is not a long hike, just a couple of minutes. Bonus tip: After you visit this amazing cliff go and check out a local restaurant called Fiskastykkið. They have some delicious fish soup worth trying.
