Leaf peeping

Leaf peeping is an informal term in the United States and Canada for the activity in which people travel to view and photograph the fall foliage in areas where leaves change colors in autumn, particularly in northern New England, Appalachia, the Pacific Northwest, and the upper Midwest, as well as the provinces of Ontario and Quebec. An organized excursion for leaf peeping is known as a foliage tour or color tour.

A similar custom in Japan is called momijigari (紅葉狩). In Finland, the season is ruska and a trek is called ruskaretki.
