Finland's outdoor landscape is organised around 187,888 lakes, primeval forest, and the Arctic — a combination that produces an outdoor culture of unusual depth. The Koli National Park in North Karelia is the landscape that inspired the Finnish national romantic movement — painter Eero Järnefelt and composer Jean Sibelius came here for the lake view from the ridge — and it remains one of the great panoramic hill walks in the country. Oulanka National Park in northern Finland carries the Karhunkierros (Bear's Ring Trail), 82 kilometres through gorges, hanging bridges, and river rapids with the largest population of wolverine in Finland. The Aavasaksa hill above the Arctic Circle is the furthest south point in Finland where the midnight sun is visible, and the summer walk there at 11pm in still-bright light is quietly extraordinary. Tours by locals often reveal the rhythm of the place in a more natural way. The hidden gems usually do the rest.
