Puerto Tranquilo is a small, tourist-oriented town in Patagonia, situated on the shores of Lake General Carrera. This location on the Carretera Austral and its proximity to Laguna San Rafael National Park make it a popular travel destination.
The town's most famous attraction is likely the marble caves at Lake General Carrera.
The peak tourist season in Puerto Tranquilo is from December to February, when the town is bustling with visitors, many of whom are Chileans. Outside of this high season, the town sees very little activity, and many businesses close during the winter months.
Lake General Carrera is the largest lake in Chile and the second largest in South America, following Lake Titicaca. In Argentina, it is known as "Lago Buenos Aires," and it reaches depths of up to 580 meters.
The calm bay on the Río Tranquilo, in contrast to the often rough waters of the lake, was used as a landing stage early on. This tranquil bay gave the town its name, which translates to "harbor on the calm river."
