Stockholm is a very walkable city, and it has a long history to tell to its visitors. I can very much recommend you to get on a walking tour with Verde Verde Travel. Stefan Maurbakken is the owner and guide of Verde Verde Travel and has been a tour guide for many years. Taking a tour with him is an experience that will stay with you for a long time.
The storytelling he does is fantastic, and you can really picture yourself going back in time. I have been on many tours with him, to places I thought I knew well but apparently didn’t. The walks are fun to do, often just with a small group of people. I think he has a limit of approx 20 participants in each group. Walking with him in Old Town is inspiring. The Old Town was once almost all of Stockholm. Today it seems to be very odd and strange, and a walk here will allow you to learn more about old times problems. Another great thing about walking with Stefan is that a tour runs for about one hour and a half, giving you plenty of time to discover more on your own. Take a look here to see which tours are available now.
