How to get there


López Hut – Open all year round.

Manfredo Segre Hut – Open from November to April.

  • Between July and December you need an ice axe and crampons, only for those with lots of mountaineering experience.
  • Check the conditions of the trail and register with the hut keeper.
  • Recommended to hire a mountain guide.


This traverse is best done as of February when there is less snow on the upper area. Until that date special gear and lots of experience are required.

Although the trail can be done in both directions, this is the most recommended, heading up from the López Hut, passed “La Hoya” bowl up to the ridge of López peak. Pay attention to all the markings and watch your step as there are lots of loose rocks. This first part is pretty steep and lots of scrambling.

From the ridge the descent is also on loose slate rocks at first down to a first valley, one of the basins to the Goye creek. Past the valley you ascend up to the Bailey Willis peak, continue along the ridge line for quite a while until you start to view the “Negra lagoon” and the Manfredo Segre Hut behind it on the shore. Head down towards the lagoon and go around on the left, there are a couple of sections with rope to help get past the steep walls. A few more meters and there is the hut.

From the Manfredo Segre Hut, also known as “Italia”, you can return to Colonia Suiza by the traditional ascent route that borders the Goye creek.

If you go in the opposite direction, you can continue on after a short stop at the López Hut down to the road on the Circuito Chico.

To improve the trekking experience, it is recommended to contact a Mountain Guide authorized by the AAGM (Argentine Association of Mountain Guides)
