Start from the Viados Mountain Hut.
(S) Head down from the refuge and keep left to reach Bordas de Viados, below the refuge.
(1) Turn right at the junction.
(2) Cross the stream and begin the climb through the forest towards Collado de Eriste (also known as Collado de la Forqueta).
(3) The route leaves the main path and the ‘Ruta de los 3 refugios’ signposting to take a short detour to the right towards Lake Ibon de Millares (steep climb before reaching the lake)
(4) Begin the only section of the route where the path is rather poorly signposted and not always easy to follow. The climb takes you between boulders to a small pass before descending again to rejoin the main path.
(5) Continue the ascent, which ends at the pass reached after a final stretch over rocky ground (the highest point of the route).
(6) Carry on down the other side, starting with a winding descent that levels out near Lake Ibon de Llardaneta. Continue the descent, following the ‘Ruta de Los 3 Refugios’ signposts.
(7) At the junction, leave the GR®11.2 and take a path that branches off to the right, crosses the stream and winds its way between boulders before emerging into greener terrain and leading to the Angel Orus Refuge (E).
