Hiking trail in Bariloche, Río Negro, Patagonia, Argentina
Cerro Catedral Summit Trek
Argentina's premier ski mountain transforms in summer into a challenging high-altitude trek through rocky terrain to panoramic Andes views. The summit reveals glaciers, multiple lakes, and Chile's border peaks on clear days.
The Cerro Catedral Summit Trek ascends Patagonia's best-known ski mountain during the southern summer, reaching an altitude of approximately 2,388 metres above sea level in Nahuel Huapi National Park, roughly 20 km south of Bariloche in Río Negro Province. The trailhead is located at the base of the Catedral Alta Patagonia ski resort on the Villa Catedral road, reached by bus from Bariloche (line 55, approximately 45 minutes) or by private vehicle with free parking at the resort base. No permits are required beyond the standard national park fee.
The route covers approximately 12 km round trip with 1,000 metres of elevation gain, typically requiring 5 to 6 hours. The lower section follows ski runs and forest tracks through dense coihue and ñire beech woodland before transitioning to open rocky terrain above the treeline. The surface changes substantially with altitude: lower trails are packed dirt; above 1,800 metres, the terrain becomes loose scree, exposed rock slabs, and — in early season (November) — potentially icy couloirs where crampons or microspikes provide a significant safety benefit.
At approximately 1,550 metres, Refugio Lynch offers food, drinks, and emergency shelter during the trekking season (December–March). Hikers can also reach this point via the ski resort's summer gondola (teleférico), effectively bypassing the lower 600 metres of ascent. From Refugio Lynch, the upper trail climbs across the Catedralito plateau before making the final rocky push to the summit ridge. Cairns mark the route above the treeline where formal signage is limited.
At the summit, clear-weather views extend across the Andes to the Chilean border, over Nahuel Huapi Lake and the Llao Llao Peninsula below, and north to the symmetrical cone of Volcán Lanín (3,776 m) on the horizon. Multiple glacial lakes are visible in the valleys, including Lagos Gutiérrez, Mascardi, and Moreno. Conditions at the summit are fully exposed to prevailing westerly winds — effective wind-chill makes warm layering essential even in midsummer. The descent retraces the ascent route.

- Multiple glacial lakes

Tips
- Crampons or microspikes may be needed on the upper section in November and early December when ice patches persist; check current conditions at the Bariloche park office before setting out.
- The summer teleférico (gondola) operates on a limited schedule and allows hikers to reach Refugio Lynch without ascending the lower ski-run section — confirming hours at the resort before the trip is advisable.
- Start early — summit clouds build rapidly after noon, and afternoon thunderstorms are common in January and February.
- The summit ridge is fully exposed to Patagonian westerly winds; a windproof shell and warm mid-layer are essential regardless of valley-level temperature.
- Download the Nahuel Huapi national park trail map, as some junctions above the treeline are marked only by cairns.
FAQ
Can beginners attempt the Cerro Catedral Summit Trek?
The hike is rated challenging due to the 1,000 m elevation gain and rocky upper terrain. Reasonably fit hikers without technical climbing experience complete it regularly in summer, but sturdy boots, appropriate layering, and a realistic time budget are essential.
Is the gondola available for hikers in summer?
The Catedral ski resort operates its gondola on a limited summer schedule, typically December through February. Hikers can use it to reach the mid-mountain area, though operating days and hours vary — confirming with the resort in advance is advisable.
Are there food and water options on the trail?
Refugio Lynch at mid-mountain provides meals and hot drinks during the trekking season. Above the refugio there are no services; carrying adequate water is important as stream sources become sparse on the upper rocky section.
What specific gear is recommended for this hike?
Sturdy hiking boots with ankle support, trekking poles, sun protection, and a windproof outer layer are essential. Crampons or microspikes are advisable in early season (November–December) when ice may remain on the upper trail.
Accessibility
The Cerro Catedral Summit Trek is not accessible to wheelchair or stroller users. The terrain above the ski resort base involves steep dirt tracks, loose scree, and exposed rock slabs. The gondola reaches mid-mountain but the platform areas are designed for ski resort use rather than accessible trekking.
When to visit
December through March is the recommended trekking window, with January and February offering the most stable conditions. November can include snow and ice on the upper trail requiring additional equipment. Avoid the hike during winter ski season (June–September).
