Isla Navarino and Cape Horn
Isla Navarino is the southernmost inhabited island on Earth (excluding research stations), separated from Ushuaia, Argentina by the Beagle Channel. Home to Puerto Williams—the world's southernmost town (2,000 people, beating Ushuaia by 40 km of latitude)—and the legendary Dientes de Navarino trek, this remote Chilean island represents Patagonia's absolute edge.
Isla Navarino & Cape Horn
Magallanes Region, Chile — The Ultimate Southern Frontier
Overview
Isla Navarino is the southernmost inhabited island on Earth (excluding research stations), separated from Ushuaia, Argentina by the Beagle Channel. Home to Puerto Williams—the world's southernmost town (2,000 people, beating Ushuaia by 40 km of latitude)—and the legendary Dientes de Navarino trek, this remote Chilean island represents Patagonia's absolute edge. Cape Horn (Cabo de Hornos), the southernmost point of South America's mainland archipelago, lies 100 km south—a windswept rock where Atlantic and Pacific oceans collide. For centuries, Cape Horn was sailing's most feared passage; today, it attracts adventurers seeking to stand at the "End of the World." The island combines extreme remoteness (no road access—boat or plane only), indigenous Yaghan heritage (the southernmost native people), world-class trekking (Dientes Circuit rivals Torres del Paine technically), and pioneering atmosphere. Wildlife includes sea lions, penguins, albatross, and Andean condors. This is for travelers who've "been everywhere" and want the ultimate southern experience—raw, challenging, unforgettable.
Why Visit
Trek the Dientes de Navarino Circuit — Argentina's most technical and remote multi-day trek: 5-7 days circling jagged peaks, scrambling passes, camping beside alpine lakes. Harder than Torres del Paine's O Circuit, with complete solitude.
Reach Cape Horn — Stand at South America's southernmost point where oceans meet. Witness legendary cape's wind-battered cliffs, memorial to lost sailors, seabird colonies. Bucket-list achievement.
Experience world's southernmost town — Puerto Williams: naval base turned frontier town. Yaghan indigenous museum, Antarctic research center, end-of-world atmosphere. More authentic than touristy Ushuaia across the channel.
Encounter Yaghan culture — Learn about indigenous people who survived naked in canoes through Patagonian winters—humanity's southernmost native culture. Museum and occasional community visits.
Wildlife at the edge — Sea lions, Magellanic penguins, imperial cormorants, Antarctic skuas, Andean condors, albatross (including wandering albatross—11-foot wingspan). Marine mammals abundant in Beagle Channel.
Pure adventure remoteness — No roads connect to mainland. Limited services. Self-sufficiency essential. For hardy travelers seeking true wilderness challenge at world's end.
Getting There
By Air (Most Common):
From Punta Arenas: DAP Airlines flies Punta Arenas ↔ Puerto Williams (1.5 hrs, several weekly, ~$200-300 USD round trip). Small propeller planes (20-30 passengers), spectacular views over Darwin Range and Beagle Channel. Weather-dependent—cancellations common (wind, visibility). Book 2-4 weeks ahead summer; reconfirm 48 hrs before.
By Ferry:
From Punta Arenas: Transbordadora Austral Broom operates ferry "Yaghan" (monthly, 30-hour crossing through Strait of Magellan and Beagle Channel, ~$150-200 USD per person + vehicle costs if bringing car). Cargo/passenger hybrid. Departs once monthly roughly. Book far ahead: www.tabsa.cl.
From Ushuaia, Argentina: Irregular crossings by private boats. More common are boat tours from Ushuaia that visit Navarino briefly (day trips, don't allow trekking). Check with Ushuaia tour operators.
Important: No regular passenger ships. No drive-on ferry from Argentina. Access deliberately difficult—adds to remoteness appeal but requires planning.

Deep snow, short days (9-5), brutal cold. Utterly isolated. Puerto Williams services limited but operational. Only for: Hardcore winter specialists.
Where to Stay
Puerto Williams:
Budget:
Refugio El Padrino: Backpacker hostel, dorms and privates, kitchen, social (dorms ~$20-25, privates ~$60-80). Popular with Dientes trekkers.
Residenciales: Family homes renting rooms (~$40-60 per person with breakfast). Ask at tourist info kiosk near plaza.
Camping: Informal wild camping outside town (ask permission). Very basic.
Mid-Range:
Lakutaia Lodge: Best option on island—comfortable rooms, restaurant, hot showers, tours organized (~$150-250 per night with meals). Located slightly outside Puerto Williams. www.lakutaia.cl

Wild camping only. Bring everything. No refugios, no facilities.
Cape Horn:
Lighthouse keeper family (not for tourists). Day trips only.
Best Time to Visit
December-February (Summer Only Practical Season): Only time most activities feasible. Temps 8-15°C days (warmest "summer"), 2-8°C nights. Wind ferocious year-round but manageable these months. Dientes Circuit snow-free (mostly). Cape Horn trips have best success rate (still 50/50 weather). Longest daylight (5 AM-11 PM). Wildlife active. Puerto Williams services fully operational. Book flights/lodging 1-2 months ahead. Still challenging conditions—expect wind, rain, cold—but survivable. January-February slightly warmer than December.
March-April (Autumn): Shoulder season. Colder (5-10°C days), shorter days, more storms. Dientes Circuit increasingly snowy/dangerous by late March. Cape Horn trips reduce success rate. Fewer tourists (almost none). For hardcore only. Some services close April.
May-November (Winter-Spring): Extreme. Winter (June-Aug): Snow buries trails, days 9-5 light, brutal cold (0-5°C days, below freezing nights), fierce storms. Dientes Circuit completely closed (impassable). Cape Horn impossible. Puerto Williams quiet—military and researchers only. Spring (Oct-Nov): Improving but still cold/snowy. Late November approaching summer conditions. Not recommended unless seeking ultimate isolation and properly equipped.

Where to Go Next
1. Ushuaia, Argentina (Across Beagle Channel)
Distance: 40 km across water (no ferry—must fly/boat Punta Arenas route)
Why Go: "Twin" city—Argentina's southernmost. More developed tourism: restaurants, hotels, shops. Tierra del Fuego National Park trails, Beagle Channel tours (different section), End of World Train, king crab dining. Creates "southernmost cities" comparison. Both claim "world's southernmost"—depends on definition.
Access: Fly Puerto Williams → Punta Arenas → Ushuaia OR charter boat direct (expensive).
2. Punta Arenas (Gateway Back to Civilization)
Distance: 240 km north (1.5 hrs by air)
Why Go: Return to Chilean mainland. Resupply, penguin colonies (Cabo Vírgenes, Parque Pinguino Rey), maritime museums, Strait of Magellan. Staging for Torres del Paine (4-5 hrs drive). Budget 2-3 days.
3. Antarctica (November-March)
Why Go: Some Antarctic cruises depart Ushuaia, fewer from Punta Arenas/Puerto Williams. If at world's end, consider ultimate journey—crossing Drake Passage to Antarctic Peninsula. Cost: $5,000-12,000 USD for 10-21 day cruises. Book: 6-12 months ahead. Creates ultimate expedition: Patagonia → Cape Horn → Antarctica.
Planning Your Route:
Extreme South Circuit: Ushuaia (5 days) → fly Punta Arenas → fly Puerto Williams (Dientes 7 days, Cape Horn) → return Punta Arenas → Torres del Paine
Ultimate Patagonia: Torres del Paine → Punta Arenas → Navarino/Cape Horn (8-10 days) → optional Antarctica
Dientes-Only Focus: Fly Buenos Aires → Punta Arenas → Puerto Williams (7 days with trek) → return
Timing Tips:
Visit ONLY December-February (other months too extreme for most)
Budget 7-10 days minimum (trek + buffer for weather delays)
Flights cancel frequently—build 2-3 day buffer
Cape Horn trips have 50% success rate weather—don't count on it
Dientes Circuit requires expert backpacking skills, navigation, self-rescue ability
This is NOT for beginners—serious consequences if underprepared
Bring satellite phone/emergency beacon (no cell service)
Register with carabineros before Dientes trek
Tell someone detailed itinerary
Weather changes FAST—be prepared for everything
Most remote destination in this entire guide—plan accordingly
Final Note: Isla Navarino and Cape Horn represent Patagonia's ultimate challenge. Not for casual travelers or those seeking comfort. For adventurers who've exhausted other destinations and crave something genuinely extreme—this is it. The reward: standing at South America's absolute edge, testing yourself on the Dientes Circuit, and earning the right to say you've been to the End of the World.
