Laguna Verde sits at approximately 4,090–4,100 meters above sea level in the western portion of the Tinogasta department of Catamarca province, Argentina. It occupies the floor of an endorheic basin — a closed drainage system with no outlet — and is part of the broader Salina de la Laguna Verde complex. The lake lies close to the Paso de San Francisco and the less-accessible Paso Tres Quebradas, both of which connect to Chile.

Paddling on Laguna Verde is not permitted. Provincial tourism authorities explicitly state that the laguna is not suitable for navigation or swimming, citing its delicate natural equilibrium and the sensitive ecological conditions that give the water its distinctive coloration. The color results from the interaction of minerals, microorganisms, and high-altitude light. Visiting the lake as a visual destination is the recommended approach.

Access requires leaving Ruta Nacional 60 at Pastos Largos — reachable from Tinogasta at km 1321 or from Fiambalá at km 1369. A Vialidad road maintenance camp at Pastos Largos is a useful stop to check road conditions before proceeding. The route continues through the Valle del Chaschuil, past a Guanaco Reserve, a Gendarmería checkpoint at Cortaderas, and a provincial police post at Laguna Verde itself. Camping is available at the police post location.

Given the high altitude, remoteness, and restricted access to the water, anyone traveling to this area should plan accordingly for extreme conditions typical of the Andean puna environment.
