Þríhyrningur Mountain Hike: A Private Journey Through Saga Landscapes
Steep trails, wild highlands, and the living history of the Icelandic Sagas await above the Flosadalur valley.
The Þríhyrningur private hike takes you deep into one of South Iceland's most storied yet overlooked mountain landscapes, tracing ancient sheep paths through untouched highlands with panoramic views over Þórsmörk, Fjallabak, and the South Coast. This is not a groomed trail experience — it is raw, rewarding wilderness walking on a mountain that carries real weight in Iceland's cultural memory. The entire tour runs approximately four hours and is graded moderate in difficulty.
Situated roughly ten kilometres inland from Hvolsvöllur, Þríhyrningur sits well outside the standard tourist circuit. That distance from the crowds is precisely what makes it remarkable: the silence is genuine, the terrain is unmanicured, and the sense of solitude that defines classic Icelandic wilderness travel is fully intact here.
The nearby Flosadalur valley is directly tied to Njáls Saga, one of the most celebrated works in Old Norse literature. It was here that Flosi Þórðarson assembled his band of men before the burning of Bergþórshvoll, an act that stands as one of the saga's defining dramatic moments. Walking these ridges means moving through a landscape that Icelanders have regarded as historically charged for nearly a thousand years.
The route follows old sheep trails rather than marked footpaths, climbing steeply to an elevation gain of 512 metres over a five-kilometre distance. Conditions vary with the weather, and the views from the upper reaches — when skies are clear — stretch across a remarkable sweep of volcanic Iceland.

How the Hike Unfolds
Your guide collects your group and provides a briefing on the trail conditions, terrain, and the saga history embedded in this corner of South Iceland. Travel time to the trailhead is short from the Hvolsvöllur area.
The approach takes you into the lower reaches of Flosadalur, the valley immortalised in Njáls Saga. Your guide introduces the events that unfolded here and what they meant to the communities of medieval Iceland.
The climb begins in earnest as you follow ancient animal paths upward through untracked highland. The gradient is consistent and the terrain requires care, rewarding steady progress with increasingly expansive views.
At 512 metres of elevation gain from the base, the summit offers views across Þórsmörk, Fjallabak, and the South Coast. On clear days, the perspective across southern Iceland is exceptional.
The descent retraces the route at a comfortable pace, with opportunity for further conversation about the landscape and its stories. The full tour, including transit, runs approximately four hours.
