Laguna Los Perros in the northern part of Torres del Paine National Park is a small lake with the large Glacier Perros flowing into it. It's one of the many highlights of the Full Circuit trek, which takes 8-10 days to complete, along with Paso John Garner, which looks out over the sprawling Glacier Grey.

Perros offers a campsite for hikers and did used to have a refugio, but sadly this burnt down a couple of years ago. To find out more, read our guide to Torres del Paine.
