The mountain that goes by the name of Hreppsendasúlur extends to the west up from Lágheiði heath, high and majestic with its two columns rising 1,052 metres into the sky. They are easily visible from the township of Ólafsfjörður. Seamen have over the ages used the mountain to get their bearings when offshore outside of Ólafsfjörður. When the two columns (‘súlur’) appear from behind the Ólafsfjarðarmúli promontory, they speak of being located ‘out on the súlur’. When you hike up the mountain there are many routes to choose from. One route begins at the emergency shelter at the Lágheiði heath. The course is taken towards the ridge to the left of the summit of the mountain. This route is very well passable, but when you get close to the summit you have to deal with some scree. It is also possible to take a longer route to the summit and then you start from Hreppsendaá river and follow the mountain spur in the direction of the Súlur mountain. From the summit, you have a good view over all of Ólafsfjörður, the Reykjaheiði heath and the Klaufabrekknadalur valley. The mountain view is strikingly beautiful over to the Fljót area to the farms Þrasastaðir and Deplar and there is also view down to lake Stífluvatn. To the south you have a view into Hvarfdalur valley and in favourable weather conditions you can see the caps of the mountains located on the east side of Svarfaðardalur valley, such as mount Kotafjall, mount Skeiðsfjall and Búrfellshyrna mountain.
