Jultayu is a smaller summit, because it does not surpass the 2.000 meters (ascend until the 1.940 meters), but by location, panorémica from its top and facility of access més of this zone of Tips of Europe is one of the ascents of interesting average difficulty.

Fertile valley of Aryan is reached about the lake of the Ercina. We crossed stands out it that there is in front of the parking and by a marked affluent footpath (left) we entered ourselves in a dismasted precipice that ascends until a col. Always by the same way, now in descendent sense, we arrived at majada from the Bobias (0h.50'). They are several cabins in good state in the middle of a meadow. In its opposite end we found a source reconstructed (0h.55') before entering a small hayedo. The way is well noticeable and it allows us to cross without problems the forest. In land once cleared, it descends until a hole where a stream flows. 1h. Is The Llaguiellu (15').

In this point a duro is faced section of ascent (the Reblagas), stony and bare, before arriving at a high well-known like the Campizas (1h.35'). It is a good point to take a rest. The way is with landmarks and some painting mark well noticeable, reason why he is fécil to follow. Jous' crosses without losing height a zone of ` (holes) well-known as the Birches (it is not left nor sign of them) and it approximates us to the col of the Jitu. The cleared top of the Jultayu is seen the bottom (right).

The final section of ascent is pending. It is surpassed drawing up ample zigzag that leaves in the viewpoint (2h. us00'). Two piles of stones and one table of direction allow us to identify main summits of the Central Bulk, that is opened before us in all its splendor.

It has service of kitchen and there is a near source.

The ascent to the Jultayu is not difficult. We followed the way that in slight reduction goes towards the Channel of Trea (right). Little después (2h.45') arrives at an intersection, where two crossings recorded on the rock indicate the dividing one between Asturias and Leon. In this point the ascent begins. It is a footpath that crosses the edge. Sometimes it is lost, but numerous landmarks help us to follow the direction until the top (3h.40'). The Vista is sensational. It faces, separated of the tremendous emptiness of the Throat of the Cares, is in favor the Central Bulk or the Urrielles. To our side (UNDER) the Towers of the Cornión rise.

The return has a variant. If we followed towards the right in the direction of Cuvaciente, we will happen next to a natural eye, ` the Juracaó, from where Caín is seen. Més is comfortable to descend to Fertile valley of Aryan and to return by the ascent route (7h.00').
