Lake Pielinen in detail
Boats ply the lake in summer. The Lieksa–Koli Ferry takes cars between Koli and Lieksa, while the passenger-only Hydrofoil Express Suvi links Koli, Lieksa and little Vuonislahti.
Buses link Lieksa and Nurmes; elsewhere you'll need your own wheels.
A winter ice road crosses between Vuonislahti and Loma-Koli (8.5km east of Koli village), cutting out 60km by road.
