Linnansaari National Park
This scenic national park consists of Haukivesi lake and hundreds of uninhabited islands; the main activity centres around the largest island, Linnansaari, which has marked trails. As well as the seals, rare birds, including ospreys, can also be seen. The best way to experience the park is renting a kayak and spending a few days exploring.
Karhunkierros Trek & Oulanka National Park
The Karhunkierros (Bear’s Ring), one of the oldest and best-established trekking routes in Finland, offers some of the country’s most breathtaking scenery. It is extremely popular in summer but it can be walked practically any time between late May and October.
Just a 15-minute ferry ride from the kauppatori (market square), a visit to Suomenlinna, the ‘fortress of Finland’, is a Helsinki must-do. Set on a tight cluster of islands connected by bridges, the UNESCO World Heritage site was originally built by the Swedes as Sveaborg in the mid-18th century.
