In 1949 50 Canadian beavers were introduced into Tierra Del Fuego, to improve the fur trade, and because there are no natural predators the beaver population continued to grow out of control. They have destroyed large sections of the park and are now considered an invasive species. We didn't see any but got some good views of their "work". Go Canada!
We enjoyed our time in the hostel making homemade meals and meeting new people. One really nice couple from Australia are on a similar trip to ours except they are on route to Canada! We told them they could stay with our friends and family, so heads up! After 4 days in Ushuaia we took a 12 hr bus to Puerto Natales in Chile, the town closest to Parque Nacional Torres del Paine.
