Laguna Esmeralda
Tierra del Fuego
Laguna Esmeralda is a picturesque glacial lake located in the Tierra del Fuego region of Argentina, near Ushuaia. Its distinctive milky turquoise color results from glacial meltwater from the nearby Ojo del Albino Glacier, which feeds the lake. The lagoon is set amidst pristine Patagonian wilderness, surrounded by lenga forests and dramatic mountain landscapes, making it a favored destination for hikers and nature lovers. The lake's formation and current size have been influenced by the glacier's retreat over recent decades, which has expanded the lagoon and shaped its unique rounded form. Visitors typically access Laguna Esmeralda via a scenic trekking route through the Tierra Mayor valley, offering a moderately challenging day hike of approximately 9 to 10 hours roundtrip. The trail passes through varied terrain including forested areas, streams, and rocky sections, culminating in spectacular views of the glacier and the lagoon. In late summer, icy conditions on polished rocks near the glacier can increase the difficulty of the ascent. The area is notable for its ecological value and natural beauty, providing opportunities for wildlife observation and photography in a relatively untouched environment.

Historia
Laguna Esmeralda and the adjacent Ojo del Albino Glacier have undergone significant changes over recent decades due to glacial retreat, which has enlarged the lagoon to its current size and altered its drainage patterns.
Originally named "Ojo de Albino" in 1989 by local trekking guide Gustavo Giorgis, the lake was smaller and noted for its milky white waters.
The glacier's meltwater continues to shape the lagoon's unique appearance and ecology.
The area has long been part of the natural heritage of Tierra del Fuego, with increasing interest as a trekking destination emerging in recent decades as access improved and tourism developed.
