The village Sandavágur lies on the south-coast of Vágar.
The church in Sandavágur lies in the city-centre and has a distinctive architecture. It was built in 1917.
In the church there is a rune stone. The inscription on the stone tells that the Norwegian Torkil Onandarson from Rogaland was the first settler on this place. The stone is said to be from the 13th century.

Excavations in Sandavágur have revealed ruins from the middle ages.

The word ‘Sandavágur’ means sandy creek and refers to the beach down by the inlet.

East of Sandavágur there is a freestanding rock called ‘Trollkonufingur’. This means ‘Witch’s finger’. It is said to have been climbed only once:
King Frederik the 8th of Denmark visited the islands in 1844. When he passed by ‘Witch’s finger’ in his ship a man had climbed the rock and was waving to him from the top. When the man had descended from the rock he realized that he had forgotten one of his gloves on the top and decided to climb it once again. On his way to the top he fell down and died.

Sandavágur takes turns in hosting an annual civic-festival called Vestanstevna. The other villages also taking their turns are Vestmanna, Miðvágur and Sørvágur. The festival is similar to Olavsøka in Tórshavn but smaller. It runs in the beginning of July.

Tradition says that two witches lived by the lake of Fjallavatn. One of them was old and partly paralysed. One day that witch laid her red gown out in the sunshine. A man from Sandavágur came by on his horse. He saw the gown, took it, and hurried away towards the village of Miðvágur. The old witch cried for help and the other one came and started chasing the thief. She caught him up and grabbed the gown. The gown broke and the man on the horse continued with one sleeve. Now they were close to the village and the church was in sight. Hence the witch had no more power and had to return. But the sleeve that the man got was so huge that it was cut into four peaces and was used as altar cloth in the four churches on Vágar.
