Leaving Ushuaia westbound along National Route 3, we move from the urban fringe into increasingly natural surroundings, where modified habitats give way to more intact landscapes—an ecological transition that introduces the region’s bird diversity before entering the national park.

This open area was cleared during the early 20th century by prison labor, leaving a wide clearing known locally as the “cemetery of trees.” The landscape blends extensive peat bogs, meadows, and patches of remnant forest—creating a mosaic of habitats that support species adapted to open environments and wetland edges.

Located on the coast of the Beagle Channel, this section offers a rare blend of mountain, sea, and evergreen beech forest. We explore BEAGLE shoreline trails under the canopy, searching for woodland and coastal species framed by one of the park’s most scenic settings.

Walking along the Lapataia River, we reach Lake Acigami (Roca), a glacial lake nestled between forested slopes. This area provides great opportunities to spot forest specialists and waterfowl in tranquil, sheltered coves.

The tour concludes in Lapataia Bay, a landscape marked by beaver-modified wetlands, rugged coastline and deep Nothofagus forest. It's also the end of the Pan-American Highway, and a prime location to appreciate how diverse and resilient this environment is.
