Three days
Spend day one in central Trevelin, the Regional Museum and a Welsh tea house. Keep day two for Nant y Fall, local vineyards or the Tulip Field in season. Use day three for Los Alerces National Park.
Five or seven days
Add Esquel and La Trochita, a full day in Los Alerces and rural areas such as Lago Rosario or Sierra Colorada. A seven-day stay also gives you room for changing weather.
