Just 20 kilometers (12 miles) from Ushuaia, hidden among peat bogs, lenga forests, and the rugged peaks of the Fuegian Andes, Laguna Esmeralda is the most popular hiking trail in Tierra del Fuego. Its striking emerald-green waters—colored by glacial sediment carried down from the Ojo del Albino Glacier—have made it one of the most iconic landscapes at the End of the World. In this guide, you’ll find everything you need to know before your hike: how to get there, how long the trail takes, its level of difficulty, what to pack for each season, and whether it’s better to hike independently or join a guided tour.
Where Is Laguna Esmeralda and How Do You Get There?
Laguna Esmeralda is located in the Tierra Mayor Valley, about 20 km (12 miles) northeast of Ushuaia, along National Route 3 toward Garibaldi Pass. The trail begins at the access point known as Valle de los Lobos (Valley of the Wolves), next to Refugio Solar del Bosque.
There are three ways to reach the trailhead:
- By car: A 25–30 minute drive from downtown Ushuaia via National Route 3. A small parking area is available beside the highway.
- By taxi or private transfer: Several local transfer services offer round-trip transportation with a prearranged pickup time.
- On a guided tour: Includes hotel pickup and drop-off, a certified guide, equipment, and insurance. This is the best option in both summer and winter, especially if it’s your first hike in Tierra del Fuego. You can book the Laguna Esmeralda Premium Trek with daily departures from Ushuaia.
The Trail: Distance, Duration, and Difficulty
- Distance: 9 km (5.6 miles) round trip (4.5 km / 2.8 miles each way).
- Duration: Approximately 4 to 5 hours at a relaxed pace, including time for photos and short breaks.
- Difficulty: Moderate. You don’t need to be an experienced mountaineer, but the terrain is uneven, with exposed roots, muddy sections, and peat bogs—known locally as “castoreros” because they are often shaped by beaver activity. The final stretch is the most demanding.
- Elevation gain: Approximately 250 meters (820 feet).
The trail begins in a beautiful forest of lenga and ñire trees before crossing the Esmeralda Creek. It then passes old beaver ponds and opens into the vast peat valley, where the surrounding mountains come into view. The reward at the end is the stunning Laguna Esmeralda, with the impressive Ojo del Albino Glacier rising in the background.
A local tip: Mud is part of the experience year-round. Even in the middle of summer, waterproof hiking boots are highly recommended. Regular sneakers will almost certainly end the day soaked.
When Is the Best Time to Visit? Summer vs. Winter
During summer (November through March), the trail is fully accessible, daylight lasts up to 17 hours, and the lagoon displays its signature emerald-green color at its most vibrant. You can learn more about hiking conditions during the warmer months in our article about summer at Laguna Esmeralda.
In winter (June through September), the lagoon freezes over and the valley becomes blanketed in snow, creating an entirely different—but equally breathtaking—landscape. However, the trail disappears beneath the snow, making navigation much more challenging. For this reason, we strongly recommend visiting only with a certified guide and snowshoes during winter. Our guided excursion includes all the necessary equipment.

Can You Hike Laguna Esmeralda Without a Guide?
Yes. During the summer season, the trail is free to access and can be hiked independently.
That said, there are three situations where joining a guided tour is highly recommended:
- Winter or snowy conditions: The trail becomes difficult to follow, and rescue operations due to hikers getting lost are not uncommon.
- If you don’t have a car: A guided excursion simplifies transportation with convenient hotel pickup and scheduled return times.
- If you’d like to learn about the area: Local guides enrich the experience by explaining the region’s beavers, peat bogs, native forests, wildlife, and the history of the Tierra Mayor Valley.
Our Laguna Esmeralda Premium Trek includes hotel transfers, a certified mountain guide, trekking poles, and a boxed lunch, all in small groups for a more personalized experience.
