The archipelago can be accessed from downtown Stockholm.
Most of the large islands can be reached by car, bicycle or SL (public transport) bus, at some locations through free-ride car ferries. http://www.trafikverket.se/Farja/Farjeleder/Farjeleder-i-ditt-lan/Farjeleder-i-Stockholm213/
The major shipping companies are the public-transport Waxholmsbolaget, and the private-owned Strömma.
Waxholmsbolaget's regular boats stop at most docks, and tickets are comparably cheap. They also have two old-fashioned steamboats, mainly for dining cruises. http://www.waxholmsbolaget.se/visitor/archipelago-traffic/plan-trip/
Strömma is aimed at major tourist destinations, faster but costlier. http://www.stromma.se/en/Skargard/Stromma-Kanalbolaget/
The Baltic Sea ferries offer an elevated view of the archipelago.
Outdoor bathing and hiking. Rod fishing is allowed without a license at most locations.
Most boats in regular traffic have a simple bar, offering regular beer and wine.
