Some of the most popular islands are connected to the mainland by bridges or tunnels and can therefore be reached by bus and car. Others can only be reached by passenger-only ferry from Stockholm as the islands are completely car-free.  You can also reach some of the islands by kayaking which you can rent in Stockholm or some of the islands. There are also one-day and multi-day organized kayaking tours you can take from Stockholm to get closer to nature. The main ferry docks in Stockholm that offer trips to the archipelago are Strömkajen in central Stockholm, where you can catch the Vaxholmsbolaget ferries and Strandvägen where the Cinderella ferry company docks. The latter usually take longer and are more expensive than Vaxholmsbolaget. Once on the islands, the best way to get around is by foot or by renting a bike as most of them are car-free.
