Probably the most popular hike in Ushuaia. Easy and beautiful. Remember to bring a jacket as it is significantly colder here than in Ushuaia
Great walk through the forest, ending with a very steep climb up to the lake. Beautiful scenary, lots of birdlife and incredible to see both Mount Olivia & Cinco Hermanos so close. The waterfalls on the way up (Cascada Velo de la Novia Ushauia) are not to miss!
I estimate that it would take about another 2 hours return to Cerro Cloche (which is the South), and would be a very easy walk as you are already at a similar altitude.
