A bald quartzite ridge over Lake Pielinen in North Karelia, its view painted by Eero Järnefelt in 1911 and picked by Sibelius for his honeymoon. Birch and aspen cloaking the 347-meter summit's slopes turn gold and copper in early October, the park's single busiest week of the year.

A 546-meter fell in the Saariselkä range, on the western edge of Urho Kekkonen National Park in Lapland. The bare summit is a two-kilometer climb from the Kiilopää fell center, and in early September the dwarf birch and willow on its lower slopes turn copper against grey scree above the tree line.

Logged for tar and timber from the 1600s until UPM donated the last tract in 2001, this Kymenlaakso forest of pine and birch is now laced with granite-walled lakes below the Olhavanvuori cliff, a near-vertical 50-meter drop into Lake Olhavanlampi. The Lapinsalmi suspension bridge crosses the narrows nearby.

Straddling the Russian border near Kuusamo, this 270-square-kilometer park follows the turquoise Oulankajoki river through pine and spruce forest, its banks lined with birch that turns gold against the evergreen canopy. The Kiutaköngäs rapids, an 8-km round trip from the visitor center, are the classic short walk; local tradition in Kuusamo marks 12 September as the day ruska arrives.
