Ólafsfjarðarmúli is one of the most magnificent mountains in Ólafsfjörður fjord. It is the fjord's outpost and reaches a height of 970 metres. The overall mountain view in Ólafsfjörður is rugged and the view from Múlakolla mountain covers almost the whole fjord, over to the Eyjafjörður and far out to the ocean. You can see houses on Grímsey island and on a good day you can see the steam plumes rise into the air from the hot springs of the Mývatnssveit region. The hike up this huge mountain that rises up from the sea is not very difficult, but it is however quite an uphill climb that needs to be overcome. You start the uphill hike north of Brimnesá river and you hike uphill on land initially covered with vegetation. When you have finished the first uphill climb, you see a number of small ponds and from these you continue straight up a hilly area until you reach a scree which is quite difficult if you take that route. It is preferable to go to the right closer to mount Kistufell and then it is even possible to walk through snow up into the Gvendarskál basin. From there you then walk along a ridge towards the northeast in the direction of Múlakolla mountain. There are some ruins of a structure built by a private party who received TV channels and retransmitted them into the town. There is a beautiful view in all directions and nobody will feel cheated by going this way it is a wonderful place for skiers in the springtime when they can ski down this high mountain to the main road. A shorter route up on the Múlakolla mountain would be from the road from Mígindi a little north of Mígindislækur brook. This route is quite steep and some places you need to proceed with great precaution. The old Múli road can be hiked but during heavy rainfall in the summer of 2004 the road was cut off and it has become very difficult to clamber across this place, but experienced hikers can easily hike the route. From the Múlavegur route, the view is beautiful and the route is very interesting and you have a good view into the valleys of Ólafsfjörður in the west, the Hvanndalabjarg cliff and Fossdalur valley, and Grímsey island.
