What this means for your visit
A good week for the viewpoints and sunset at the Marco das Três Fronteiras. A chill of 9°C calls for a real coat, especially early in the morning and at night. The likelihood of full capacity at attractions is shown in Will it be full? and the live bridge queue in Bridge queue.
