Colico (Comasque: Còlich [ˈkɔlik] or Còlegh [ˈkɔlek]; Latin: Colicum) is a town and comune in the province of Lecco, in Lombardy in northern Italy.

Near Colico is an important natural reserve, the migration corridor of the Pian di Spagna (in the province of Como).

The two main waterways of Colico are Inganna and Perlino; the river Adda is a natural boundary between the provinces of Como and Lecco.

On the northern Montecchio hill are still visible two guard towers, which formed the so-called Castle Colico, built in the Medieval commune period to control the road from Valtellina.

The most important from a strategic point of view was Fontanedo Tower, part of a more complex work of fortification built during the 14th century by Visconti.

Another part of the defense system is Fortino d'Adda, or Stallone, located out of the border municipalities in the territory of Gera Lario.

Roccoli, or bird snares, are tree architectures, equipped with nets placed vertically, which surround a sort of stone tower from which the hunting was run.

Of the many bird snares active until about forty years ago, are still well preserved those located near Piona and along the road that goes up to the Fort Fuentes.

The line was then operated by the Adriatic Network, one of three major companies that remained in effect until 1905, year of birth of the Ferrovie dello Stato.
