There are many coves and points shaping beaches and cliffs, creating a perfect shelter for sea fauna.
Lake Roca, opposite Mounts Condor and Guanaco, lies in the south of the park. It flows into the sea at Lapataia Bay through Lapataia River, a short turbulent watercourse. This practically virgin, especially protected area in the north of the park encompasses the central part of
.
The forests in Tierra del Fuego National Park are like no other. Peat bogs, made up of a dense layer of moss and other organic matter, are plentiful in the island ecosystem besides the rest of the flora with native species such as
ñire, lenga , Magellan’s beech and cherry trees.
Old man’s beard hanging from tree branches is a familiar sight, as is reddish moss. Flowers can be enjoyed throughout the year be they the eye-catching red flowers of the Chilean firetree, crowberries or yellow violets.
Numerous birds inhabit the forests such as the Magellan woodpecker, the Magellan goose and the Austral conure. Among the mammals, red and gray fox,
guanacos, sea otters and beavers (an exotic species).
Many marine invertebrates such as mussels, limpets and winkles as well as much appreciated crustaceans such as spider crabs can be found among the rocks on the coast of the Beagle Channel. The puyén and peladilla, as well as the sea bass are native fish.
The park holds testimonies of the people who inhabited
Tierra del Fuego before the arrival of the white man: the Selk’nam or Onas, the Haush or Manek’enk, the Alakaluf and the Yámana or Yahganes. Near the coast there are archeological sites with
‘conchales’ or
‘concheros’ (accumulations of shells), piles of mollusk valves and animal remains of the Yámana staple diet.
There are two ways of reaching the Beagle Channel: a two-kilometer road to
Bahía Ensenada, from where
Isla Redonda (Round Island) can be seen or along Bahía Lapataia until the end of Route 3.
The bay, the cove,
Isla Redonda and
Canal Estorbo, Les Eclaireus Lighthouse and Ushuaia can all be admired from a catamaran that leaves from Puerto Arias. Bridges Islands (
De los Pájaros and
De los Lobos – Birds and Sea Lions Isles) can also be reached.
Should you continue by land, after crossing River Lapataia, Ovando and Cormoranes archipelago you will reach the Interpretation Center and the Yámana ‘conchero’ (accumulation of shells) from where a great variety of sea birds as well as isolated groups of sea lions and porpoise can easily be spotted.
The park offers opportunities for trekking lovers. Two interpretive trails can be accessed from the Interpretation Centre:
Laguna Negra (Black Pond), which traverses a peat bog and
Sendero de los Castores (Beaver Trail). Visitors who prefer a longer hike can set off along a four-kilometer trail leading to milestone XXIV, which marks the border with Chile, or a two-kilometer trail to Pampa Alta, from where they will enjoy a panoramic view of the Beagle Channel, Yendegaia Bay in Chile, Isla Redonda and Ushuaia and Ensenada Bay.
Tierra del Fuego National Park is a must see destination for visitors to the City of Ushuaia, not only because of the variety of activities it offers, but for its amazing biodiversity as well.
