Dientes Circuit | Isla Navarino, Chile, 1997

Distance :  33 miles (53 km)a_2

Avg.Time :  3 or 4 days

Start / Finish :

  • Puerto Williams
  • Isla Navarino can be reached by both regular plane and boat services from Ushuaia (Argentina) or Punta Arenas (Chile).
  • In 1997 I flew down from Punta Arenas and hitched a ride back to Ushuaia on a yacht. To this day (November, 2013), it remains the only time I have ever hitched a lift with a yacht. Have to say, it was pretty cool.

Seasonality :  December to March

Maps / Info :

  • I used the map and trekking notes contained in Lonely Planet Trekking in the Patagonian Andes (1992). The most recent edition of this excellent guidebook came out in Novemer, 2009.
  • If you are looking for greater detail, try the following two Chilean IGM 1:100,000 maps: Puerto Williams – L #190 and Lago Windhond – L #203. You can purchase these maps in Santiago at the IGM Sales office. Alternatively, click here to purchase online from the IGM website (in Spanish).
  • It is possible to buy supplies in Puerto Williams, but you will find a wider range and cheaper prices in Ushuaia or Punta Arenas.

Route / Conditions :

  • The route is reasonably well marked throughout. A combination of cairns, paint splashes and the occasional bit of tape/ribbon show the way.
  • Much of the trek is above tree line. Navigating is not difficult in fine conditions, however, due to the notoriously  unpredictable nature of weather patterns in this part of the world, careful attention should be paid to route finding at all times. Proficiency with map and compass is a must.
  • The one negative of this hike is the prevalence of beaver ponds and dams throughout the island’s valleys. It is estimated that there are 20,000 of the furry little buggers on the island, and with no predators, both their numbers and negative influence are bound to grow exponentially in the coming decades.



  • From a hiking perspective, this means some of the circuit’s low-lying areas are often waterlogged and very muddy.
  • Any water taken from such low-lying sources should be purified or treated.

Sleeping :

  • No huts. Bring your own shelter. Be sure that it will hold up in the harshest of conditions.

Overview :

  • Jagged rock pinnacles, hundreds of lakes and gorgeous views throughout. Outside of Antarctica, the world’s most southerly hike.
