The Senda Costera trail from Lago Roca to the post office is 8 km long and leads mostly through forest in its western section. If you don't want to hike back the same way and don't want to hitchhike, I recommend starting at the post office, hiking west for as long as you like, and then walking back to the post office. I find this eastern section the most beautiful.

The hike to Laguna Esmeralda is a true highlight for anyone wanting to experience the rugged beauty of Patagonia. The trail leads through dense forests, past rivers and marshy areas that can be quite challenging in the rain. Sturdy footwear is essential, especially in wet weather, as the muddy terrain demands both sure footing and patience. But it is precisely this variety of paths, from wooden boardwalks to small inclines, that makes the hike so diverse and exciting. The lake itself lies nestled between snow-capped peaks, its emerald-green water appearing almost unreal. I found the transition between the wintry mountain landscapes and the vibrant colors of the water particularly impressive – an almost meditative experience. The landscape here changes rapidly, constantly offering new perspectives, whether through the mist that suddenly rolls in or the view of the surrounding glaciers looming in the distance. A personal tip: If you have the time, you should also visit the nearby Laguna Turquesa – a fantastic addition to the hike that offers even more breathtaking views. However, be prepared for the typical Patagonian weather changes. What starts as clear visibility can quickly turn into fog and wind, significantly impacting the view of the lake. Despite the often challenging conditions, this hike remains one of my favorite experiences in this region, an impressive journey not only for experienced hikers but also for nature lovers. The feeling of finally seeing Laguna Esmeralda after the final climb is unforgettable and well worth every effort.
