Archipelago National Park
The labyrinthine Archipelago Sea, off Southwestern Finland, has more islands than any other archipelago in the world. It has also been described as the world's most beautiful archipelago. The archipelago scene varies from larger islands dotted with rustic pastures and vibrant villages, to wild and windswept rocky islets. Scheduled ferry services take locals and trippers to the main islands all year round.
Suitability: Since the national park is only accessible by sea, a visit requires thorough planning. No services for visitors with mobility difficulties.
