As you lace up your boots to explore Argentina's breathtaking landscapes, understanding how to acclimatize properly will enhance your adventure and keep you safe from altitude sickness. Whether you’re scaling the peaks of Mendoza or trekking through Patagonia, this guide will arm you with the knowledge you need for a successful outdoor experience.
Your adventure begins in Buenos Aires, the vibrant capital city. To reach the mountainous regions where acclimatization becomes essential, take a domestic flight to Mendoza (approximately 2 hours). Aerolíneas Argentinas and LATAM offer round-trip prices ranging from 15,000 to 20,000 pesos (around $45-$60). Once in Mendoza, you can rent a car from the airport for about 3,500 pesos ($10.50) a day, or take a taxi to the city center for around 600 pesos ($1.80).
For those heading south to Patagonia, consider flying to El Calafate. Flights are available for 20,000 to 30,000 pesos ($60-$90). El Chaltén, the trekking capital, is a three-hour bus ride away (costing about 3,000 pesos or $9). In both Mendoza and El Chaltén, local transport options like buses and shared taxis are easily accessible, making it simple to get around and reach trailheads.
In Mendoza, book a stay at Hostel Lagares, where prices start at 5,000 pesos ($15) per night. This place is ideal for meeting fellow trekkers and sharing tips. Alternatively, for a bit more comfort, the Hotel Diplomatic offers cozy rooms with prices starting at 12,000 pesos ($36) and is conveniently located near the city center.
In El Chaltén, consider staying at Los Glaciares National Park Lodge for around 10,000 pesos ($30), providing easy access to popular trails like Laguna de los Tres. A more budget-friendly option is the Chaltén Hostel, where dorms begin at 4,500 pesos ($13.50). Regardless of where you stay, ensure your accommodation has good heating—night temperatures can drop significantly!
Fueling your body is crucial for acclimatization. In Mendoza, head to La Central for a traditional Argentine asado (barbecue). A parrilla (grill) meal costs about 3,000 pesos ($9) and includes a hearty selection of meats, which is perfect for recovering after a day of hiking. Pair it with a glass of Malbec for an authentic experience—wines here are fantastic and can be found for 1,500 pesos ($4.50) a bottle.
In El Chaltén, visit La Tapera for delicious homemade pasta and pizzas, with prices around 2,500 pesos ($7.50). Don't miss the local craft beers at Chaltén Beer House, where a pint costs about 800 pesos ($2.40). Staying hydrated is crucial, so carry a refillable water bottle—most restaurants will happily refill it for you. If you venture into the trails, pack dehydrated meals from local markets for quick energy boosts.

Generally, you should allow 2-3 days to acclimatize to altitudes above 2,500 meters (8,200 feet). It's advisable to ascend gradually, spending a day at mid-level altitudes to prepare your body. Most trekkers find that taking regular breaks and staying hydrated significantly helps the acclimatization process.
Common symptoms include headaches, nausea, dizziness, and fatigue. Be on the lookout for more severe symptoms like a shortness of breath or confusion. If you experience any of these symptoms, it’s crucial to descend to a lower altitude immediately and seek medical attention if symptoms persist.
