The start of the route is at the Cabana Curmătura viewpoint. This can be reached via several trails, including the ‘Gaining height in Piatra Craiului National Park’ walk described here.
(S/E) Pass via the west terrace of the viewpoint and walk 50 metres to the start of a path marked by a sign indicating ‘Spre Saua Padinei Inchise 2h30’.
(1) Head northwards up through the forest. Markings (blue lines) are present. The path turns north-west. Follow it to a barely visible junction with an unmarked path that climbs steeply up the scree slope.
(2) Ignore the track heading north and continue north-west, then south-west. You will reach a high point.
(3) Descend a few metres until you reach the centre of a couloir.
(4) Make a mental note of this spot to avoid getting lost on the descent: do not go too far down this couloir. The climb up the couloir may require you to use your hands. After a right-angled bend, continue to the pass.
(5) The return journey follows the same path in the opposite direction back to the viewpoint. (S/E)
