Lónsöræfi is a mountainous wilderness in south-east Iceland. There are colourful mountains rising over 1300 m, wide rivers, glacier tongues from Vatnajökull. It's good for hiking. The trail Snæfell– Lónsöræfi is passing through the area. You can explore other valleys too. The area has three huts, and when heading for mount Snæfell (1833 m) one will come along more huts.
