The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva, Navarino, Hoste, Londonderry and Stewart.

The Channel separates the main island of the Tierra del Fuego archipelago from the islands of Oeste, Navarino, and other smaller islands lying to the south of it.

On the shores of the strait are the communities of Ushuaia, Puerto Williams and Puerto Toro, considered the southernmost in the world. There is also the world's southernmost lighthouse, which is a tourist attraction.

The strait is named after the ship "Beagle", on which Charles Darwin rounded South America during his famous voyage.

The strait is narrow, in some places only 5-6 kilometers.

Like the Strait of Magellan, Beagle Strait is peaceful. And the Cordillera-Darwin, adjacent to the strait in the northwest, with a glacier field on the highest mountain in the archipelago, makes it a popular tourist destination. During a hike along Beagle Strait, you can see seals, penguins and cormorants.

The Beagle Channel, named after the HMS Beagle which sailed through it in the 1830s, is a narrow waterway in the Tierra del Fuego archipelago at the southern tip of Argentina. It has been a vital transportation route for centuries and is surrounded by stunning scenery.

According to local legend, the Beagle Channel was created by the giant serpent known as Yámana. It is said that Yámana created the channel by slithering through the mountains and hills, carving out a path for the sea to flow into the land.

The Yámana people were the first inhabitants of Tierra del Fuego and believed that the Beagle Channel was a sacred place. They believed that the channel was created by the gods and that it was the gateway to the underworld. They also believed that the channel was home to a giant serpent, which they called Yámana.

The Yámana people would travel through the channel in their canoes, leaving offerings for Yámana to ensure a safe passage. They would also tell stories about Yámana and the other spirits that inhabited the channel.

Today, the Beagle Channel is a popular destination for tourists and explorers, who come to admire the stunning scenery and learn about the local history and legends. It is also an important transportation route for ships traveling between Argentina and Chile, and a vital part of the region's economy.

The legend of Yámana and the creation of the Beagle Channel serves as a reminder of the rich cultural heritage of the Tierra del Fuego region, and the importance of preserving its natural beauty for generations to come.
