Árnafjall, Mountain peak in Vágar, Faroe Islands

Árnafjall is a mountain on the west side of Vágar in the Faroe Islands, rising to 722 metres (2,369 ft) above sea level. It stands north of the village of Gásadalur, and the island's next-highest peak, the 715-metre Eysturtindur, lies to the south-east. A separate Árnafjall on Mykines reaches only 350 metres.

Árnafjall rises 722 metres on the west side of Vágar, making it the highest mountain on that island, though among all 18 Faroese islands it ranks only 37th in height. The name, meaning "eagle mountain", is shared with a 350-metre mountain on neighbouring Mykines. The island's next-highest peak, the 715-metre Eysturtindur, lies to the south-east.

The name Árnafjall translates from Faroese as 'eagle mountain'. The same name is also given to a separate, lower mountain of 350 metres on the neighbouring island of Mykines, so the two are often distinguished by island.

Árnafjall rises west of Gásadalur, on the western side of Vágar, and the summit stands at 722 metres. The nearest higher peak on the island, Eysturtindur at 715 metres, lies to the south-east. Plan for wind and rain at the top, since the upper slopes are exposed and the weather shifts quickly.

The mountain shares its name with a 350-metre peak on Mykines, the island visible to the west; the two Árnafjall are often confused. On Vágar it is the island's highest point at 722 metres, while the island's next-highest summit, Eysturtindur, reaches 715 metres to the south-east.
