Laguna Esmeralda

A stunning emerald-colored alpine lake surrounded by jagged peaks and offering one of the most popular day hikes from Ushuaia. The moderate trek through beech forests rewards hikers with breathtaking panoramic views of the Beagle Channel and surrounding mountains.

Things to do

• Laguna Esmeralda Summit Hike — Trek the moderate 9 km round-trip trail through southern beech forest to reach the emerald alpine lake at approximately 600 meters elevation with panoramic views of jagged peaks.
• Beagle Channel Viewpoint — From the lake's shores, enjoy unobstructed vistas of the Beagle Channel and distant Chilean peaks across the water, especially striking in clear afternoon light.
• Photography at Peak Light — Capture the distinctive emerald coloring of the glacially-fed lake during golden hour when mineral-rich water reflects the afternoon sun most brilliantly.
• Forest Botany Walk — Identify lenga and ñire beech species, southern fagus trees, and endemic Fuegian flora along the well-marked trail during the hike.
• Picnic Lakeside — Pack local provisions and enjoy a meal on the rocky shores of Laguna Esmeralda while surrounded by jagged mountain peaks.
• Wildlife Observation — Watch for Magellanic woodpeckers, southern caracaras, and occasionally guanacos in the beech forest and alpine meadows around the lake.

Food to try

• Centolla (King Crab) — A signature Fuegian delicacy harvested from the Beagle Channel, typically served steamed or grilled in Ushuaia restaurants before or after your hike.
• Trucha Ahumada (Smoked Trout) — Locally-caught trout from Tierra del Fuego's pristine rivers and lakes, smoked and available at regional markets and lodges.
• Cordero Fuegino (Patagonian Lamb) — Tender lamb raised on Fuegian grasslands, typically grilled or slow-cooked and served in Ushuaia establishments.
• Calafate Berry Desserts — Native purple berries from southern Patagonia made into jams, pastries, and desserts available in local shops as trail snacks.
• Empanadas Caseras — Traditional Argentine hand-held pastries filled with lamb, beef, or cheese, readily available at Ushuaia bakeries for trail provisions.

Local customs & good to know

• Start Early for Weather — Tierra del Fuego weather changes rapidly; begin your hike before 8 AM to ensure adequate daylight and to avoid afternoon wind and cloud cover.
• Respect the Beech Forest — The southern beech forest is protected; stay on marked trails, take all trash with you, and avoid picking plants or disturbing wildlife in this delicate ecosystem.
• Layer Your Clothing — Temperatures at the lake drop significantly compared to Ushuaia; locals and experienced hikers recommend waterproof jackets and thermal layers year-round.
• Check with Local Guides — Many Ushuaia outfitters offer guided hikes with expert knowledge of flora, history, and safe route-finding; hiring a local guide supports the community.
