Sendero Hacia Esmeralda
The hike to Laguna Esmeralda is about 9 km round trip and takes roughly 3 to 4 hours, depending on your pace.
The trail starts around 20 km outside of Ushuaia and is relatively flat but can get very muddy, especially in the forest section.
You'll walk through lenga forests, peat bogs, and open valleys with great mountain views.
At the end, you reach the glacial lagoon, which has a striking turquoise-green color due to the minerals from the melting glacier.
It's a popular trail but still feels peaceful, especially if you go early in the morning.
