Cerro Tronador Day Trip from Bariloche: Glaciers in the Ski Season
Cerro Tronador is an 80 km day trip from Bariloche to a 3,478-metre extinct volcano with a dramatic hanging glacier -- the most spectacular single-day excursion from the city during ski season.
Cerro Tronador is a 3,478-metre stratovolcano on the Argentine-Chilean border, 80 km southwest of Bariloche, and the most dramatic single-day excursion available from the city during ski season. The main draw is the Ventisquero Negro -- a hanging glacier that descends the volcano's eastern face and drops glacial ice onto a terminal moraine at roughly 900 metres elevation. The round-trip from Bariloche covers about 160 km on mostly sealed road and takes the better part of a day, but the scenery is unlike anything visible from the ski resort network.
What is Cerro Tronador and why is it worth a day trip from Bariloche?
Cerro Tronador (Spanish: Thunderer) is the highest peak in the Nahuel Huapi region at 3,478 metres, straddling the Argentine-Chilean border. It is an extinct stratovolcano with five glaciers, the most accessible of which -- the Ventisquero Negro -- sits at the end of the main access road at around 900 metres elevation. The name comes from the booming sound made when large blocks of ice calve from the glacier and fall onto the rocks below. On a clear winter day, Tronador is visible from Bariloche as a white cone above the southern lake district ridgeline, roughly 80 km away. The glacier, surrounding lenga beech forest, and the scale of the volcano's southern face create a combination of landscapes entirely different from the groomed ski resort environment.
How do you get to Cerro Tronador from Bariloche?
Most visitors take a guided day tour departing Bariloche between 8 and 9 am, returning by 6 to 7 pm. Organised tours cost $60 to $90 USD per person and include transport, park entry, and a guided walk at the glacier. Self-driving is also practical: take Ruta Nacional 258 south from Bariloche to Villa Maschwitz, then follow the signs into Nahuel Huapi National Park toward Pampa Linda. The last 25 km from Pampa Linda to the Ventisquero Negro parking area is unsealed but passable in a standard 2WD vehicle in dry conditions. In wet or icy conditions, 4WD is advisable. National Park entry costs $8 to $12 USD per person for foreign visitors and is payable at the park gate.
What is the Ventisquero Negro and what does it look like up close?
The Ventisquero Negro (Black Glacier) gets its name from the dark rock dust and debris covering its lower section, making the ice appear almost black from a distance. Up close, the glacier's terminal face reveals pale blue-grey ice beneath the debris layer, and the sound of calving ice can be heard regularly from the viewpoint. A signed walking trail leads from the parking area to the main viewpoint in about 20 minutes on easy terrain. The full approach walk to the glacier terminal moraine takes 45 to 60 minutes and involves some rough ground. In winter, the surrounding beech forest carries heavy snow on its branches, creating a distinctly Patagonian winter scene. The calving events that give the mountain its name occur most frequently in warmer afternoon hours -- plan to be at the viewpoint between noon and 3 pm if you want to hear the glacier.
What can you do at Cerro Tronador in winter?
The standard activity is the walk to the Ventisquero Negro viewpoint (20 minutes from parking, easy terrain). More active visitors continue to the glacier's terminal moraine (45 to 60 minutes, rough ground, waterproof boots required). A snowshoeing option is available from the Pampa Linda clearing -- a 2 to 3 hour circuit through the forested valley floor. Ice climbing at the glacier face is available for experienced climbers with certified guides. Photography is the dominant activity: the Tronador massif, the black-and-white glacier contrast, and the southern lenga beech forest make a visually striking combination. There is a seasonal refugio at Pampa Linda that may operate a basic cafe in winter -- bring food and hot drinks as insurance.
How much does the Cerro Tronador day trip cost?
A guided day tour from Bariloche costs $60 to $90 USD per person, typically including bus transfer, National Park entry ($8 to $12 USD), and a guided walk at the glacier. Self-driving saves the tour cost but adds fuel (approximately $15 to $20 USD round-trip) and requires National Park entry paid separately. Snowshoe hire at Pampa Linda, if available, runs $15 to $20 USD. Budget $80 to $100 USD for a full guided day including all costs, or $35 to $50 USD self-driving with your own food and park entry.
Is the Cerro Tronador road open during ski season?
The main access road via Pampa Linda is generally open year-round but can close temporarily after heavy snowfall or in extreme wind events. The national park administration office on Avenida San Martin in Bariloche maintains current road status. Guided tour operators monitor conditions daily and will reschedule if the road is closed -- check the rescheduling policy before booking. In a typical July or August, the road is open on most days, though access to the upper viewpoints may require snowshoes after fresh snowfall. The Pampa Linda parking area is ploughed regularly in season.

Frequently Asked Questions
Is Cerro Tronador worth a full day trip from Bariloche?
Yes, particularly for skiers taking a rest day or non-skiers wanting a dramatic Patagonian winter experience. The Ventisquero Negro and the surrounding national park scenery are genuinely unlike anything at the ski resort. The drive itself, through the lake district with Nahuel Huapi on one side and forested ridgelines on the other, is worthwhile in clear weather.
Can you hike to the glacier at Cerro Tronador in winter?
The viewpoint walk (20 minutes, easy) is accessible in most winter conditions with standard walking boots. Reaching the glacier terminal moraine (45 to 60 minutes) requires waterproof boots and care on rough, potentially icy terrain. It is not a technical climb and does not require crampons in most conditions -- but check with your guide or the park administration before the longer approach in winter.
Is Cerro Tronador an active volcano?
No -- Cerro Tronador is classified as an extinct stratovolcano with no eruptive activity in recorded history. The name comes from the sound of calving glacier ice, not volcanic activity. It is part of the same southern volcanic zone as nearby active volcanoes Lanin and Calbuco but poses no volcanic hazard.
Can I combine a Cerro Tronador trip with skiing the same day?
Not practically. The round-trip from Bariloche takes 8 to 10 hours, leaving little time for meaningful skiing. Plan Tronador as a dedicated rest day. It pairs naturally with a non-ski rest day in Bariloche or as a mid-trip buffer between heavy ski days. See also our non-skier guide to Bariloche for more rest-day ideas.
