The most popular excursion on Lago Nahuel Huapi is the 30-minute boat ride from Puerto Pañuelo on the Península Llao Llao to Isla Victoria, the largest island in the lake. A grove of redwoods transplanted from California thrives in the middle of it. Walk on trails that lead to enchanting views of emerald bays and still lagoons; then board the boat to sail on to the Parque Nacional los Arrayanes. Boats go daily at 10 am and 2 pm (more frequently in high season). The earlier departure includes time for lunch on the island in a cafeteria-style restaurant. The later departure is a shorter trip. Vessels are run by Cau Cau (Mitre 139, Bariloche 2944/431–372 www.islavictoriayarrayanes.com) and Turisur (Mitre 219, Bariloche 2944/426–109 www.turisur.com.ar).
