These fine mineral particles, suspended in the water, reflect sunlight in a unique way, creating the lagoon's mesmerizing hue.The hike to Laguna Esmeralda is a rewarding experience in itself. The trail winds through a fairytale lenga forest, where shallow-rooted trees often lie uprooted, evidence of the area's extensive beaver population. The landscape then opens to expansive peat bogs, crossed by log paths to ease passage, before reaching the stunning lagoon.At Laguna Esmeralda, the views are simply spectacular. The serene, emerald-colored lake is framed by the rugged peaks of the Fuegian Andes, with the snow-capped Cerro Martial often visible in the distance.
