Los Arrayanes National Park

A forest of rare, orange-colored trees that only grow on a local island (and one in Japan) near Villa la Angostura. There are several cruise boats; the newest (luxurious) ship is called the "Cau Cau". Take the circuit bus out of Bariloche and catch a boat (near the Hotel Llao Llao) and have lunch, hike or bike, and enjoy the afternoon in the forest.
