Camping is allowed only in designated places (allowed on privately own lands in accordance with the freedom to roam), remembering to respect the domestic peace. Building campfires is allowed only in designated places, unless a force majeure situation arise. Fire-making is prohibited if a forest fire warning is in effect. One may pick berries and mushrooms. Mind roosting birds when landing on islets. Islets with many nesting birds should only be visited in autumn and winter. The Blue Mussel visitor center in Kasnäs, (Kimitoön) and the archipelago center in Korpoström (Korpo) offer information on the Archipelago Sea and the Archipelago National park. There are bus connections to both. There are nature trails on some of the islands. There is an underwater trail for divers on Stora Hästö in Korpo (and one in shallower water for snorkelers).
