Vappu is Helsinki's May Day celebration, and the whole city joins in. Students gather at the Market Square, then everyone heads to Kaivopuisto Park and Ullanlinnanmäki hill for a picnic.
For kids, it's a day outdoors in a cheerful crowd: blankets on the grass, food from home and a city in party mode. It suits families who don't mind crowds, less so kids who need quiet.
