Stockholm, Sweden
Packed with sophisticated shops (GT loves Swedish design), a diverse array of restaurants and bars, plenty of art (in museums, galleries—even throughout the entire subway system), culture (a gorgeous opera house, and, um, ABBA!) and lots of outdoor space to explore (the city is spread across 14 islands connected by walkable bridges), Stockholm is an ideal future gimlet traveler destination — especially when enjoyed during the extra-long days of midsummer.
