Viewed from Bastión de San Pedro, the southwestern most point of Colonia, this is an interesting, great natural spectacle. In the middle of February, the sun dips down during sunset right where you can find Buenos Aires at the horizon. In other words, on a clear evening it seems to sink into the Argentinian capital on the other side of the river with its skyscrapers and high buildings. If you have a good zoom, this allows for a great picture. Of course, do not look directly into the sun.
