Foliage means the wonderful autumnal landscape with the variation of warm colours of all the copse and larch woods. So, the foliage is a natural event which, thanks to the emotions it creates, focuses the attention of many fans all over the world: landscape's evalutaors, painters, photographers, trekking enthusiasts.
When yellow, red, orange, brown and purple colour the leaves of the trees, the word foliage also takes on a turistic meaning, as natural research; an activity which was born in the wide and spectacular forests in U.S.A. and which is going to become more and more frequent also in Europe.
Even Brianza provides a lot of possibilities to discover foliage (Here the list of all the parks in Brianza)
