The route begins a bit to the north of Þingvellir and to the west of the volcano Skjaldbreiður, which really comes up to its name (meaning broad shield). The track continues between the glaciers Þórisjökull and Ok and leads up to the north. To the east of Reykholt it comes near the Reykholtsdalur to Húsafell. Then it continues up to Hvammstangi at the Miðfjörður.
