Kymenlaakso is a region in Southern Finland named after the valley of river Kymijoki.
- Repovesi National Park. One of Southern Finland’s most popular hiking destinations.
- Valkmusa National Park. Large mire landscape with plenty of birdwatching opportunities.
- Gulf of Finland National Park. In outer archipelago, best explored by boat.
There are no passenger airports in Kymenlaakso but frequent connections both to Kouvola and the coastal cities by bus from Helsinki. Trains from Helsinki to all parts of Eastern Finland and Russia pass through Kouvola, and so do many bus lines going in that direction. If you're coming by road from St.Petersburg and are heading for Helsinki, you will likely cross the border at Vaalimaa, east of Hamina.
