A circular four- to five-day hike leads from Grenivík via the Látraströnd coast to the Gjögur headland, which guards the eastern entrance to Eyjafjörður, and then east through the coastal Í Fjörðum region to Hvalvatnsfjörður and the beginning of Route F839, which then returns towards Grenivík.
From Grenivík, follow the unnumbered road northwest from the village to the deserted Svínarnes farm, where the road ends and a track continues along the Látraströnd shoreline, passing several more abandoned farms, including Látur, which has been empty since 1942. The path then swings inland through the Uxaskarð pass (in order to avoid the Gjögur headland) and drops down through Keflavíkurdalur to reach the shore at Keflavík, one of Iceland’s remotest locations, a deserted farm that was regularly cut off from the rest of the country for months in the wintertime. At the beginning of the eighteenth century, people on the farm here were taken ill and died one by one as the harsh winter weather set in – all except for an 11-year-old girl, who remained alone here for ten weeks until people from the nearest farmstead finally managed to dig their way through the heavy snowdrifts to rescue her. Passing Þorgeirsfjörður, the path heads southwest for the next fjord, Hvalvatnsfjörður, and the beginning of the F839 mountain road back over the hills up to the Leirdalsheiði plateau and finally down into Grenivík; there can often be snow along this route until the middle of July.
