El Calafate is a magical door leading to the impressive world of glaciers. El Calafate is in the province of Santa Cruz, almost 200 miles (316 km) away from Río Gallegos, the province's capital. It's located by the shores of Lake Argentino, Patagonia's largest lake, which covers an area of 566 square miles (1,466 sq km), and has an average depth of 490 feet (150 m). There's an International airport, El Calafate, around 15 miles (23 km) away from the center, with direct flights to Buenos Aires, Bariloche and Ushuaia, among other cities. The place is named after the calafate plant, a local evergreen shrub. The legend has it that whoever eats its berries will come back to the city at some time for some more. The weather is predominantly dry, with average high temperatures of 66 °F (19 °C) in the summer and average low temperatures of 28 °F (-2 °C) in the winter. Surrounded by mysteries and facts, visitors to El Calafate are able to witness the secrets of the eternal ices and the undiscovered and most amazing parts of Argentina's geography. The tourist center is the starting point for tours going to glaciers such as Upsala, Onelli, Viedma, Agassiz and world famous Perito Moreno, among others. Main tours and excursions include a visit to Nimes Pond —an amazing wildlife reserve— a nautical tour and mini-trekking over Perito Moreno Glacier, excursions to Lake Roca and visits to Walichu Cave, where you'll view an ancient example of Patagonian cave painting. Among willows, pines, cypresses, poplars and calafates, this city warmly welcomes thousands of tourists from all over the world, who, upon leaving, always have the desire to return.
