Esmeralda Lagoon is one of the most beautiful spots in Ushuaia. Located about a 40-minute drive away, it is reached by an early-morning pickup (around 8:30 AM) and a drive to the trail entrance. The standard duration of the hike each way is about 2.5 hours. We suggest wearing trekking shoes or boots. If you don't have them, you can rent them in the city. Shoes are really important because the trail is uneven and includes a peatland area. Another detail to keep in mind is to not forget a waterproof jacket.
