Lago Sofía, also referred to as Laguna Sofía, is a lake located near Puerto Natales in the Magallanes and Chilean Antarctica Region of southern Chile. It sits within a landscape of mountains and cliffs, with the Cerro Benitez viewpoint offering elevated perspectives over the lagoon and the surrounding Patagonian steppe.

The lake is accessible through Pingo Salvaje, a tourist center situated within a private residency known as Sofia Lake Ranch. This serves as the primary put-in point for paddling activities. Kayaking is the main paddling discipline practiced here, with guided tours available as half-day excursions typically lasting between 3.5 and 5.5 hours. At least one operator offers private group tours with a picnic included, and the difficulty level is rated as basic, making the lake suitable for paddlers without advanced technical skills.

The surrounding environment supports a variety of birdlife, including black-necked swans, wild geese, and ducks, which paddlers are likely to encounter while on the water. The mountainous terrain enclosing the lake contributes to a sheltered character, and the area is also used for recreational fishing and trekking, though these activities do not appear to conflict with paddling access.

The lake is described as a quiet destination, and its proximity to Puerto Natales makes it a practical day-trip option for those based in the town. Guided excursions depart from The Singular Patagonia hotel, suggesting that organized access through established operators is the standard approach for visiting paddlers. No specific restrictions or regulations unique to paddling on the lake are known.
