The hike begins at the marker post on the uppermost road bend and furthest to the north in Skarðsdalur valley. You then hike from post to post across a rather steep hillside north of Grashólabrúnir ridge until you have a view down to the Dalaskarð pass. It is possible to take a very short detour east to Snókur where you get a good view over the town of Siglufjörður. A marked hiking trail leads down to the Skjaldarbringur area and overlaps the route west to the Dalir region. At the Styrbjarnardys cairn the trail curves northeast up to the Hafnarfjall mountain, where there is a good view over the fjord. At that place, there is a treacherous precipice beneath which there are very steep cliffs above the Jörundarskálar basin. The hike takes you over an uneven gravel area and it is possible to take a shorter route down to the southern part of Fífladalir hollows and continue to the Stóriboli snow avalanche earthworks, which are located at the southern part of the town. This trail is approximately 3.5 km long with marker posts along the route. It is possible to continue the walk north along Hafnarfjall mountain and west of Hafnarhyrna mountain and the hike up the mountain is easily doable for all experienced mountaineers. From there, you will be able to see some fifty mountain peaks, summits and horns, each of which has its own name. In these parts, there is a panoramic view with few parallels in Northern Iceland. The rugged Hornstrandir coastline and the Strandafjöll mountains and the Skagi peninsula to the west, and Drangey island, Málmey island and Þórðarhöfði promontory are all inside the Skagafjörður fjord. Past the Skagagrunn bank, the Fljótamið waters and the Grímseyjarsund strait with the island of Grímsey at the edge of the sea to the north-east and further to the east are Gjögur tip and Melrakkaslétta flatland. This panorama expands as you move east along the Hvanneyrarhyrna ridge and still further north along the Strákafjall mountain, which is easily tackled by seasoned mountaineers. An easy path marked with posts leads back down towards the north-westerly bottom of the Hvanneyrarskál basin and to the basin rim above the town.
