3-Week Argentina Backpacking Itinerary on a Budget
Argentina is huge, it stretches through half the South American continent, so 3 weeks is nowhere near enough time to see it all, even backpacking at a fast pace. That’s exactly why having a solid Argentina backpacking itinerary matters: you’ll want to research where you actually want to go and build your route around flight and bus availability, since some legs only run a few times a week. It’s also worth checking the weather for whenever you’re going, since parts of the country can still see snow depending on the season. In this post, I’m walking through every stop on my 3-week route through Argentina: where I went, how long I stayed, and what was actually worth the time.
Quick Answer: 3-Week Argentina Backpacking Itinerary
Start in Ushuaia (2 days) for hiking and boat trips, then head to El Chaltén (3 days) for Mount Fitz Roy treks and El Calafate (2 days) for the Perito Moreno Glacier. Next, fly to Puerto Madryn (2 days) for whales and penguins, then finish with Iguazú Falls (2 days) and 3 days in Buenos Aires, with an optional day trip to Colonia, Uruguay. Total: about 3 weeks, moving mostly by short flights and long-distance buses.

Week 1
Ushuaia
The morning after I arrived in Buenos Aires, I already boarded my next flight. It took me to Ushuaia, one of the southernmost towns in the world. In October it can still be very cold there, temperatures were around 6 degrees Celsius. I’d recommend spending at least 2 days here. On the first day I hiked to Laguna Esmeralda, and on the second I took a boat trip through the canal and rode the train to Tierra del Fuego.
El Chalten
From Ushuaia I flew to El Calafate and took a bus to “the hiking capital,” El Chaltén. The ride took about 3 hours, and I arrived after dark. This is where all the hikes to the famous Mount Fitz Roy start. I got lucky with the weather on the day of my big hike, the other two days were cloudy and rainy. I’d planned to stay 3 days hoping at least one would be clear, and it paid off.
Week 2
El Calafate
After 3 days in El Chaltén, I took the bus back to El Calafate. From here you can visit the Perito Moreno Glacier, though it’s just one of over 800 glaciers in the region, I only had time for the most famous one. On my other day I took a tour to the Walichu Caves and the Laguna Nimez Reserve, where you can spot a variety of birds, including flamingos.
Puerto Madryn
I went to Puerto Madryn to see the whales. During winter and spring, southern right whales come here with their newborn calves because the waters are warmer than further south. One day was filled with a trip to Península Valdés and a boat excursion. Since there’s not much else to do in Puerto Madryn, I spent the second day visiting the penguins, there’s a huge colony about 1.5 hours south of town.
Week 3
Iguazu
After a one-night layover in Buenos Aires, I arrived in Iguazú to see the falls. It doesn’t really matter whether you stay on the Argentine or Brazilian side, I’d recommend seeing them from both. I stayed on the Argentine side and crossed the border on my second day, returning in the evening. Two days is really all you need here.
Buenos Aires
Back in Buenos Aires at last, I had 3 full days there. Honestly, that felt like almost too much time, so I used one of those days for a day trip to Colonia del Sacramento, Uruguay, the perfect little escape after 3 weeks in the wilderness, once Buenos Aires started to feel too busy.
FAQ: Argentina Backpacking Itinerary
Is 3 weeks enough time to backpack Argentina?
Three weeks is enough to cover a solid highlights route (Patagonia, Iguazú Falls, and Buenos Aires) but not the whole country. Argentina is massive, so you’ll need to pick a region (like Patagonia and the north) rather than trying to see everything.
What’s the best route for 3 weeks in Argentina?
A popular route starts in Ushuaia, moves north through El Chaltén and El Calafate for hiking and glaciers, then to Puerto Madryn for whales and penguins, before finishing with Iguazú Falls and a few days in Buenos Aires.
When is the best time to backpack Argentina?
It depends on where you’re headed. Patagonia is best visited from October to April (spring through fall in the Southern Hemisphere), outside that window, weather and closures make hiking harder. Puerto Madryn’s whale season runs roughly June to December.
How much does 3 weeks of backpacking in Argentina cost?
Costs vary a lot by region: Patagonia (flights, tours, gear rental) tends to be pricier than the rest of the country. Budgeting for internal flights between Patagonia towns is worth planning for early, since bus rides between some spots can take a full day or more.
Do I need to book flights within Argentina in advance?
Yes, especially for Patagonia routes like Ushuaia to El Calafate, flights and long-distance buses can sell out or run infrequently, so booking ahead gives you more flexibility with your itinerary.
Can you see Iguazú Falls from both the Argentine and Brazilian sides in one trip?
Yes, many travelers cross the border for a day to see both. The Argentine side lets you get closer to the falls, while the Brazilian side offers better panoramic views.
My name is Cory and my two favourite things in the world are traveling and scuba diving. You will either find me under the water or on top of a mountain. I have the PADI Advanced Certification and want to see as many marine animals as possible.
