Lago Gris is a serene and relatively undiscovered lake nestled in the comuna of Lago Ranco, Provincia del Ranco, in Chile's Región de Los Ríos. Sitting at approximately 500 meters above sea level, this mountain lake is embraced by temperate rainforest, native woodland, and Andean cordillera scenery, forming part of the broader lacustrine network that connects with Lago Ranco and other water bodies of the region. Despite its name, the waters of Lago Gris are notably clear rather than grey, reflecting the surrounding forests and sky in a way that makes it a visually striking destination. Its relative isolation has kept it largely free from heavy human intervention, preserving both its ecological integrity and its appeal as a quiet, natural retreat. The nearest service center is the town of Lago Ranco, which provides the closest access to supplies and amenities for visiting anglers.
