About Tresa
Municipality · Ticino
The river Tresa leaves Lake Lugano at a point between Lavena Ponte Tresa in Italy and Ponte Tresa in Switzerland and flows into Lake Maggiore near Luino, a few hundred metres after joining the Margorabbia. At the outflow from Lake Lugano the river is crossed by a bridge which unites the Swiss and Italian parts of Ponte Tresa; a customs post divides them.
