It is an amazing experience to ride in a speed boat through the icy rivers in the South of Argentina from El Calafate. The Boat sail across Patagonian Glacier and through the northern waters of Lake Argentino, gives a stunning natural landscapes of the towering ice walls and the immense icebergs of the Los Glaciers National Park. Then the boat navigates through the Boca Del Diablo, the narrowest part of the lake. Cruise up the Upsala channel towards the spectacular Glacier to watch the mesmerizing natural landscapes of the icy deep blue rivers and enormous icebergs floating past. The boat tour then continues on the Spegazzini channel, there we can see the Seco Glacier, finally reaching the highest Glacier in the National Park the Spegazzini Glacier with its spectacular steep, dramatic icescape that curves down the mountainside into lake. After this breathing adventure, the boat reach back to El Calafate. It was truly an amazing boat trip.
