Roca Lake, Ushuaia, Argentina, South America

Roca Lake is a glacial lake situated within Los Glaciares National Park, approximately 50 kilometers northwest of El Calafate, Argentina.

Visual Characteristics

The lake's water exhibits a pale turquoise to milky blue coloration, influenced by glacial silt. Its perimeter is defined by steep, rocky shores and dense subantarctic forest, primarily composed of lenga and ñire trees. The surrounding terrain features scree slopes and exposed bedrock.

Location & Access Logistics

Access is via National Route 11 (Ruta Nacional 11) for approximately 40 kilometers, then turning onto Provincial Route 15 (Ruta Provincial 15) for an additional 10 kilometers. The final section is a gravel road. Parking is available at designated areas near the lake's eastern shore. Public transport options are limited; private vehicle or organized tour is the primary method of access.

Historical & Ecological Origin

Roca Lake is a product of glacial erosion, formed by the movement of ice sheets during past glacial periods. The surrounding landscape is a result of ongoing geological processes, including erosion and sedimentation.

Key Highlights & Activities

Activities include observing the lake's coloration, photography, and short walks along the shoreline. Fishing is permitted in designated areas with a valid permit. Boat tours are not available on Roca Lake itself.

Infrastructure & Amenities

Basic facilities include a limited number of picnic tables and pit toilets. There are no food vendors on-site. Cell phone signal is generally absent.

Best Time to Visit

The best time for clear water visibility is during the austral summer months (December to February). Mid-morning to early afternoon offers the most direct sunlight for observing the water's color. Access may be restricted during heavy snowfall in winter.

Facts & Legends

The lake is named after Julio Argentino Roca, a former President of Argentina. A specific geological feature to note is the presence of glacial erratics – large boulders deposited by glaciers.
