Cerro Ñato South-East Ridge - Luce de Leche (Milky Light)


The Cerro Torre - Cordòn Adela Group is a beautiful chain located in Patagonia inside Los Glaciares National Park and lined up between Brecha Cuatros Dedos to the North and Viedma Glacier to the South. This spectacular group includes in its Northern sector some oustanding and worldwide famous granite peaks, as Cerro Torre, and some mighty ice-capped summits in its Southern sector.

Cerro Ñato is one of these latter, an attractive peak located South to Cerro Torre, between Cerro Adela Sur and Cerro Doblado. On the mighty icy spur of Cerro Ñato facing South-East it runs a beautiful ice-climb: Luce de Leche (Milky Light).

Getting There

The approach trek to Cerro Ñato starts from El Chalten, a small mountain town in Argentina, Santa Cruz Province, on the riverside of Rio de las Vueltas. The village offers some basic shops, phone, internet facilities and accomodations such as camping and beds. At the entrance of El Chalten there is a Park Office, where trekkers and climbers have to register and obtain permits (they are free: the only cost is the Park entrance fee). From El Chalten starts the trail to Cerro Torre and Cerro Fitz Roy, so during the peak summer season there is a lot of tourists, trekkers and alpinists. The village is located about 230 Km North of El Calafate, the real gateway to the Los Glaciares National Park, and the tour requires about 4 hours, on paved road (daily buses). El Calafate provides all modern facilities and all price accomodations (hotels, estancias, cabins, camping). The town is situated on the south side of Lake Argentino, about 320 km Northwest from Río Gallegos (5 hours drive on good paved road; daily regular bus services). One can fly directly to the new Calafate Airport or, alternatively, fly to the most important Rio Gallegos Airport (daily flies from Buenos Aires) and then drive for about 300 Km (5 hours) to Calafate along National Route Nr. 5.

From El Chalten a good path, following Rio Fitz Roy valley, leads to Bridwell Camp and Maestri Camp at Laguna Torre (camping place), from where a “mirador” can be reached: from here it's possible to enjoy a spectacular view on the impressive glaciers and peaks (Cerro Torre, Cerro Adela, Cerro Ñato, Cerro Doblado). The trail requires about 2,5 hours by walking. From the “mirador” a thin trail leads down on Glaciar Grande, which is crossed diagonally leftwards to gain the base of the impressive Cerro Ñato iced Southeast Ridge

The first summiters of Cerro Ñato were Ettore Castiglioni, Leo Dubosc and Titta Gilberti (Italy) on February 1937, climbing the South-West Ridge, the Normal Route (AD) starting from Paso Doblado, a saddle between Cerro Ñato and Cerro Doblado

Route Description

Cerro Ñato South East Ridge

Luce de Leche (Milky Light) Difficulty: TD inf. / 70º
Length: 900 m.
First ascent: Alberto Rampini CAAI and Davide Brighenti AGAI - (Patagonia '87 Italian Expedition) 4/11/1987

Approach: from Laguna Torre (campsites) get to the "Mirador", then descent to the Glaciar Grande and cross it slanting left towards the footh of the majestic iced ridge. The best choice is edificating an igloo or making a cave below the wall: a tent may be not a good idea in case of wind, because of the absence of repairs.

Climbing report

From the bivouac hole at the base of the mountain climb gently angled snow slopes, reaching the beginning of the ridge. Follow it, sometimes keeping a little on the left, sometimes climbing directly on the sharp ice ridge. The ridge rises up more and more steep and offers a technical climb, due to the ice quality, similar to icefall one. In the upper part of the ridge a main bergschrund provides an exciting climb on vertical-overhanging step; successively climb some steep gullies avoiding the rocks. To climb this steep sections a pair of technical axes is required. The final wall is easier on good snow. First ascent was realized in about 6 hours.

The descent route follows the South West Ridge to Paso Doblado, a long classic route (Castiglioni, Dubosc, Gilberti 1937 route, the peak's first route to be climbed and the normal one to the summit). From Paso Doblado the starting bivouac hole at the base of SE ridge is reached along the glacier between Cerro Ñato and Cerro Doblado.

Essential Gear

Rope, crampons, two technical tools each climber, ice screws. Helmet is absolutely a good choice.
