  • world’s most southerly major hike?
  • circumambulate the jagged spires of Cordon de los Dientes
  • out of Puerto William, Chile, on Isla Navarino (pop. 2,262 last time we counted)
  • recommended 5 days, 4 nights in the past. Most hikers are doing it in 4 days, 3 nights now as the trail is well cairned and signed.

Why We Like This Hike

  • great views, most of the trek is above the treeline
  • vista over the islands making up Cape Horn (about 150km south)
  • condors, guanaco & beaver may be seen
  • it’s close to Paine & Fitz Roy, our favourite hikes in Patagonia
  • no risk of altitude sickness

  • extreme weather is your greatest concern
  • prepare for howling winds & unexpected snowfall
  • hypothermia is a risk
  • scrambling & bushwhacking may be needed
  • painted stones & cairns mark the main route
  • you need a strong tent & good tie-downs to survive the wind
  • Dec to March are the best months to hike
  • for safety you should register with the police or at the Gobernacion Maritima Police office in Puerto Williams
  • benzina blanca (stove fuel) might be hard to find. Check the hardware shop next to the supermarkets.
  • there is no official rescue service. Be responsible for your own safety.
  • campsites do not provide much shelter
  • views often obscured by cloud
  • as your feet get very wet, you will be cursing the introduced beavers

  • Brian Spurling was there in 2017. He found it expensive compared with the other great Patagonian hikes.
    • ferry Punta Arenas to Puerto Williams US $167 (£130) / person (30 hrs)
    • Ushuaia (Argentina) to Puerto Williams (Chile) and on to Navarino was US$120 one way, $220 return daily with Onashaga Expeditions / person in 2017. (30 min by 12 passenger boat, 35 min bus). This price does not include the international Port Fee of $60.

Trekking Guides

Though it’s no problem to do the Circuit independently, it’s easiest to do Dientes is with a guide. We’ve not used any of these services:


You need to get to and from remote Puerto Williams. A few options:

  • Boat from Ushuaia (US$120 one way, $220 return daily with Onashaga Expeditions in 2017) … or,

  • Ferry from Punta Arenas … or,
  • Flight from Punta Arenas

Puerto Williams

The only gear store stocks some types of stove fuel, knives, tents, sleeping bags, etc. You can also rent a GPS there that has the circuit route uploaded.

Small supermarkets have basic food supplies.

Still, the more food and gear you can bring with you, the better.

Local Information

When you get to Puerto William, ask if there are any hikers who have recently returned. They will be the best source of last minute advice on trail conditions.
Hotels and hostels in Puerto Williams have all the information you need to organize the trek. Register for the adventure at the police station. There is no Ranger or trail maintenance once you get out there.
