On a narrow peninsula reaching out into Lake Lohjanjärvi, a single square kilometre of forest has been protected since 1964 in order to be something most of Finland is not — a lehto, a rich deciduous grove of linden and hazel growing on unusually lime-heavy soil. Norway spruce pushes in from the east and shades that grove out, so the forest administration periodically goes in and fells the intruders, leaving the trunks where they drop. The rotting wood is not tidied away. Deadwood is part of the point.

The small meadow in the middle of the reserve is...

Finland's everyman's right — the freedom to roam, camp and pick berries almost anywhere — is one of the country's defining liberties, and inside a strict nature reserve it does not apply. At Karkali visitors must stay on marked trails. Hunting, fishing, collecting plants, inverte...

The marked trail is laid out as nested loops of half a kilometre, one kilometre, three kilometres and six, all starting and ending at the same point beside the entrance. Only the longest reaches the tip of the peninsula, and only the longest is properly demanding; the rest are ea...

Just outside the reserve boundary lies Torhola, Finland's largest limestone cave — thirty-one metres long, thirty-six wide, with fourteen metres of vertical relief between its highest and lowest points. It was cut by water dissolving the lime out of the bedrock and leaving the ha...
