Accommodation

Accommodation in San Martín de los Andes during winter ranges from charming cabins and boutique hotels to larger resorts. Availability decreases significantly during peak ski season (July and August, especially during Argentinian winter holidays), and prices are at their highest. Booking well in advance, ideally 3-6 months, is crucial for securing desired lodging and potentially better rates. Many accommodations feature cozy amenities like fireplaces and saunas, perfect for warming up after a day in the snow.

Crowds & Tourism

San Martín de los Andes experiences its peak tourist season during winter, particularly from mid-July to August, coinciding with school holidays in Argentina. The town and especially Cerro Chapelco can be very crowded, with long queues for ski lifts and busy restaurants. Outside these peak weeks, particularly in late June or early September, crowds are more manageable, offering a quieter experience while still enjoying excellent snow conditions. Overall, expect higher crowd levels compared to autumn or spring, similar to, if not exceeding, the busiest summer periods.

Winter is the most expensive season in San Martín de los Andes.

Booking services and activities well in advance can help mitigate some costs, but overall, budget for a higher expenditure compared to other seasons.

Driving Conditions

Important for car rental travelers

Driving conditions in winter require careful attention. Roads leading to and from San Martín de los Andes, including sections of Ruta 40 and the scenic Ruta de los Siete Lagos, can be snow-covered or icy. Access roads to Cerro Chapelco often require snow chains, which are mandatory in adverse conditions, or a 4x4 vehicle. Main roads within the town are generally cleared quickly, but side streets can retain snow and ice. It is highly recommended to rent a 4x4 vehicle with winter tires or ensure your rental agency provides snow chains. Always check road conditions before departing, carry emergency supplies, and drive defensively. Self-driving offers immense flexibility for exploring the region's stunning snowy landscapes at your own pace, but safety should be the top priority.
