The best view of Stockholm's northwest! Monteliusvagen is a highly rated walk along the northern ridge of the island of Södermalm, and it'll give you a nice view of Stockholm's City Hall and the Old Town.
If you're really adventurous, follow the path till it's end and keep going to the massive bridge at the western end of Södermalm. Cross the bridge for more views and walk right into the giant park of Fridhemsplan.
Continue from there along the water all the way back to the City Hall! This incredible walk will take you at least a couple of hours, but there are plenty of restaurants (and if you're traveling during the summer) ice cream/coffee shops on the way!
