We begin at the entrance to Núpsstaðarskógar valley, immediately diving into a landscape of towering cliffs and winding side canyons. The route keeps things interesting from the start, including a short 10-meter rock climb, assisted by a chain and rope, leading us to the dramatic double waterfall of Tvílitihylur. We continue along the Núpsá river, pass another waterfall, and push up a steep gully onto the wide plateau of Sléttur, where unique lava formations mark the end of a big first day.
