Bahía Yendegaia is a bay on the northern shore of the Canal Beagle, on the Isla Grande de Tierra del Fuego in the Magallanes region of Chile. It is part of Parque Nacional Yendegaia and the Cape Horn Biosphere Reserve. The bay's coastline has dense Magellanic forests and its western side forms part of the national park's core zone. Historically, the area was inhabited for thousands of years by the Yaghan (Yámana) people, a canoeing culture who navigated these coastal waters in canoes made from Coigüe bark. Access for paddlers is currently limited as there is no public road access to the bay. The primary planned access point is Caleta 2 de Mayo within the bay, which is the terminus for the under-construction Ruta Y-85 road. Once completed, this road will provide terrestrial access from the north, but currently, the park can only be reached by boat or air. A future ferry service, the Aunashaka barge, is planned to connect Caleta 2 de Mayo with Isla Navarino, a crossing estimated to take four hours. As a bay opening directly into the Canal Beagle, paddlers must be prepared for significant exposure to the open, often harsh conditions of this major channel. Winds can be strong and fetch can be considerable, creating challenging paddling conditions and potential surf zones at the bay's entrance. Tidal currents from the Beagle Channel will significantly influence travel, requiring careful tide planning. The water is cold year-round, typical of sub-Antarctic latitudes. There are no described facilities or amenities for paddlers at the bay itself. The overall character is one of remote, pristine wilderness with high ecological and cultural value, offering a challenging expedition-style paddling experience for those who can arrange the complex logistical access.
