Patagonia’s Best Hikes: A 10-Day Backpacker’s Itinerary from El Chaltén to Ushuaia

Patagonia is one of the last places on Earth where a trail can take you from a granite spire draped in glacial ice to a windswept channel at the bottom of the world – all within ten days. This itinerary strings together the best hiking terrain across Argentine and Chilean Patagonia, moving south from the trekking mecca of El Chaltén through the raw border country near Lago del Desierto, across into Chile’s Torres del Paine, and finally down to Ushuaia on the Beagle Channel. It’s a route that demands solid fitness, a flexible mindset for Patagonian weather, and a willingness to carry your life on your back. The reward is a sustained immersion in landscapes that most travelers only see in photographs.

Day 1: El Chaltén – Arrival and the Laguna Torre Trail

El Chaltén sits at the northern edge of Los Glaciares National Park, a small mountain village with a single main street and an outsized reputation among trekkers. Arrive by morning bus from El Calafate – a journey of roughly three hours through steppe and wind – and you’ll have the afternoon light ahead of you.

After dropping your pack at a hostel or campsite, ease into the terrain with the Laguna Torre trail. The 18-kilometer round trip follows the Río Fitz Roy valley before climbing through southern beech forest to a moraine-fringed glacial lake backed by the impossibly jagged Cerro Torre. Allow four to five hours and keep your eyes on the sky – Patagonian weather can bury the summits in cloud within minutes. Evening in El Chaltén means a bowl of lamb stew at one of the village’s no-frills restaurants, which is the right way to start a trip like this.

Day 2: El Chaltén – Fitz Roy Circuit and Laguna de los Tres

This is the hike most people come to El Chaltén for, and it earns its reputation. The trail to Laguna de los Tres climbs steadily through lenga beech and open pampa before a steep, loose final push to a plateau lake that sits almost directly beneath Monte Fitz Roy’s east face. On a clear morning, the reflection of the towers in the water is the kind of sight that resets your sense of scale.

Start before 7 a.m. to beat both the crowds and the afternoon gusts. The full circuit, including a detour to Laguna Capri on the return, covers about 24 kilometers. Your legs will feel it by late afternoon, but that’s the point – this is the physical and visual peak of the El Chaltén portion of the trip. Spend the evening organizing your gear for the longer stretch ahead. You’re leaving paved roads behind tomorrow.

Day 3: El Chaltén to Lago del Desierto – Border Country on Foot

Lago del Desierto lies 37 kilometers north of El Chaltén along a gravel road that cuts through a valley flanked by glaciers and dense Patagonian forest. A shared transfer van makes the journey in about an hour. From the southern shore of the lake, a trail runs along the eastern bank through some of the least-visited forest in Argentine Patagonia – moss-covered, silent, occasionally muddy, and genuinely remote.

The hike covers roughly 14 kilometers to the lake’s northern tip, where a small Chilean border post marks the end of Argentina. Camping here is basic but the setting – a mirrored lake framed by glacier-capped peaks – makes up for any lack of comfort. This day is deliberately lower in intensity, building in a recovery window before the logistically complex border crossing to come. Bring more food than you think you need; resupply options disappear after this point for the better part of two days.

Day 4: Lago del Desierto to Villa O’Higgins (Chile) – Crossing by Boat and Boot

The crossing from Argentina into Chilean Patagonia here is one of the most unusual border passages in South America. From the northern end of Lago del Desierto, a small passenger ferry crosses Lago O’Higgins into Chile – schedules are limited and seasonal, so confirm dates before you leave El Chaltén. Once across, a 22-kilometer trail connects the lake’s Chilean shore to the small outpost town of Villa O’Higgins, passing through old-growth forest and over a short mountain pass.

The trail is well-marked but the terrain is uneven and the final kilometers before Villa O’Higgins involve a river ford that can run high after rain. Plan for six to seven hours of hiking. When Villa O’Higgins appears – a cluster of wooden houses and a gravel airstrip at the end of the Carretera Austral – the sight of it carries genuine weight after a full day on foot. Stamp your passport at the border post and find a bed at one of the town’s small hospedajes.

Day 5: Villa O’Higgins – Rest Day and the Carretera Austral’s Southern End

Villa O’Higgins is the southernmost town on Chile’s legendary Carretera Austral, the highway that threads through Chilean Patagonia for over 1,200 kilometers. There are no roads south from here – this is genuinely the end of the line, and the town wears that fact quietly. It has a small bakery, a couple of restaurants, and a feeling of purposeful remoteness that’s entirely different from the curated wilderness experience of better-known Patagonian towns.

Use this day to rest your feet, wash clothes, and eat a full meal. The Lago O’Higgins viewpoints on the edge of town reward an easy walk, and the local museum covers the settlement history of the region. Organize your onward transport here – a combination of ferry and bus connections links Villa O’Higgins to Puerto Natales via the ferry port at Puerto Yungay. The logistics require advance planning; this is the section where flexible travelers fare better than rigid ones.

Day 6: Puerto Natales – Gateway to Torres del Paine

Puerto Natales is where Patagonian trekking infrastructure concentrates. It’s the main jump-off point for Torres del Paine National Park, and the town knows it – gear rental shops, hostel common rooms full of trail maps, and restaurants calibrated to hungry hikers line the waterfront street along the Última Esperanza Sound. Arrive by early afternoon after a long transit day and use the remaining hours well.

Pick up any supplies you’re short on: freeze-dried food, gas canisters, blister tape, dry bags. Check your Torres del Paine park entry permit and campsite reservations – the park has mandatory pre-booking for campsites along the W Trek, and showing up without a reservation means turning around. If you’re carrying a tent and cooking your own food, confirm your fuel and meal plan for three nights in the backcountry. Puerto Natales has some genuinely good seafood; the king crab, locally called centolla, is worth the splurge before heading back into the wilderness.

Day 7: Torres del Paine – The W Trek Begins (Mirador Las Torres)

The bus from Puerto Natales drops you at the park entrance at Laguna Amarga by mid-morning. From there, the eastern arm of the W Trek climbs through scrub and rocky terrain to the centerpiece of the entire park: the Mirador Las Torres, a viewpoint directly below three enormous granite columns rising more than 2,500 meters above sea level. The round trip from the park gate is around 22 kilometers with 850 meters of elevation gain.

The final ascent on loose boulders demands careful footing but takes no technical skill. When you reach the top and see the towers reflected in the glacial tarn below them, the silence is broken only by wind and the occasional rumble of ice calving off the Glacier Torres above. Camp at Camp Torres or Chileno tonight – both are well-maintained and in spectacular settings. Sleeping beneath those peaks with your boots finally off is one of the better feelings this itinerary offers.

Day 8: Torres del Paine – Valle del Francés and the Heart of the W

The middle section of the W Trek crosses through the Valle del Francés, a hanging valley flanked by glaciers on one side and sheer cliff walls on the other. Moving west from Camp Cuernos, the trail enters the valley floor and climbs to a mirador with views of the Cuernos del Paine, ice fields, and a cascade of hanging glaciers that shed towers of ice with a sound like distant artillery.

This day covers around 20 kilometers and takes in more vertical variation than the previous stage. Condors are reliably spotted riding thermals above the valley walls. Camp at Paine Grande on the shore of Lago Pehoé tonight – the sunset over the grey water with the Cuernos catching the last light is the kind of image that embeds itself permanently. The camp has a basic restaurant; use it. After two days of trail food, a hot meal served by someone else feels extraordinary.

Day 9: Punta Arenas – City Stopover and the Strait of Magellan

A ferry from Lago Pehoé and a bus connection brings you to Punta Arenas, the largest city in Chilean Patagonia, sitting directly on the Strait of Magellan. After days of forest and granite, the wind-battered city streetscape and the expanse of grey water beyond it reorient your sense of geography completely. You are now at latitude 53° South, and the Antarctic feels plausible rather than abstract.

Walk to the waterfront and look south across the Strait – this is where Magellan became the first European to navigate from the Atlantic to the Pacific in 1520. The Plaza de Armas has a famous bronze statue of him, and locals say touching the toe of the indigenous figure at his feet brings good luck on journeys. The natural history museum in the regional library covers Selknam and Kawésqar indigenous culture in depth. Stay one night in the city; it transitions your mind between the intense physicality of the W Trek and the final day of hiking ahead.

Day 10: Ushuaia – Tierra del Fuego National Park and Trail’s End

A short flight or the long overland route through Chile connects Punta Arenas to Ushuaia, the Argentine city that markets itself – accurately – as the southernmost city in the world. The approach by air reveals the Beagle Channel and the Martial mountain range rising directly behind the town, still snow-capped in late spring and summer. Ushuaia is tourist-friendly in a way that El Chaltén and Villa O’Higgins are not, but Tierra del Fuego National Park at its western edge strips that away quickly.

The park’s trail network includes the Costera trail along the Beagle Channel shore and the more demanding Pampa Alta route that climbs to a plateau with views over Lago Fagnano and the Darwin Range. The Senda Costera covers about eight kilometers one way, passing through peat bog, southern beech, and beaver-altered wetland – the European beavers introduced decades ago have reshaped significant sections of the landscape in ways that ecologists are still working to reverse. Finish the hike at the trailhead beside the channel and watch the sea wind move through the kelp. The end of the road is literally marked here by a sign: Fin del Mundo. After ten days and hundreds of kilometers of some of the most demanding terrain in the hemisphere, it feels like the right place to stop.

Getting there and practical notes: The route begins with a flight to El Calafate (Argentina) and ends in Ushuaia, which has direct flights to Buenos Aires. Travel between El Chaltén and Ushuaia requires a mix of buses, ferries, and one short internal flight – book the Lago O’Higgins ferry and Torres del Paine campsites months in advance during peak season (November through March). A 10-liter dry bag inside your pack is non-negotiable in Patagonian rain. Wind is constant and forceful; poles help on exposed sections. The border crossing at Lago del Desierto requires both Argentine and Chilean visas if applicable to your nationality – check requirements before departure.
