If you’d like to see Stockholm from a boat, take one (or all) of Stockholm’s ferries that are part of the SL system. SL stands for Storstockholms Lokaltrafik = public transportation in Stockholm, Sweden.
All you need is a regular ticket – preferably a timed visitor SL Access smart card, but a single ticket will work as well (for an excellent guide about public transportation in Stockholm, see sweetsweden’s post “Your Guide to Public Transport in Stockholm“).
1) Route 80 – which, when we took it in May 2019, used to run between Stockholm Nybroplan in the Stockholm center and Frihamnen, which is close to where several large cruise ships dock when they visit the town, and took about 50 minutes one way.
It looks like since May 2019 this route was expanded to go beyond Frihammen and includes 9 more stops now, going all the way to Frösvik! (Which means if we’re ever back in Stockholm, we’ll have to take the trip again and update the post with more photos!)
