This trail begins at the parkinglot at Kastali house and from there either over the snowy slopes of Fannborg to Mt. Lodmundur. From Lodmundur to the peak of Snot and from there to the highest peak of Kerlingarfjoll - Snaekollur (1,428m). From Snaekollur to Vesturgnipa and over the passage to Fannborg. From Fannborg back to the parkinglot. This is a rather demanding walk but you are rewarded with the fabulous scenery from the peaks.
