BOUT is a taxi boat service app that has created a pilot case for the southern part of the Stockholm Archipelago, partly to service the trail.
This makes it possible to go directly between the sections of Landsort, Nåttarö, Rånö, Ålö, Utö, Fjärdlång and Ornö. Hopefully BOUT will be able to extend their service for the other parts of Stockholm Archipelago Trail too.
You can register and book a taxi boat via BOUT if you want to go directly to a section nearby.
