1. Discover Gamla Stan
First things first in Stockholm include the boisterous island of Gamla Stan, generally considered the old town of the city. The small island is compact with cobblestone lanes, impressive buildings from the 17th and 18th centuries, and modern Nordic restaurants and cafes.
By following the small, twisting lanes, you eventually emerge onto Stortorget, Stockholm's oldest and most famous square.
The area is bordered by houses painted green, red, and yellow, which you've certainly seen before because they're popular photo motives. They are widely recognized as some of Sweden's most iconic landmarks.
