Helsinki in summer is just magical, a small-scale city, spread out on islands in the Gulf of Finland. Traveling through Finland in summer, kids will enjoy long, long days that never end – the nights never really get dark.
Swimming Stadium (next to the Olympic Stadium) -The Swimming Stadium has pools for everyone, little wading pools for toddlers, big waterslides, a sauna for adults. Bring your suits, you can rent towels.
Or, do what local Helsinki families do, head for the beach at Uunisaari. Take the boat from Merisatamantori (close to the big Kaivopuisto Park). The beach has shallow water for little kids, swings and play structures. There's plenty of places to picnic, or grab a bite at one of the cafes.
