Koper, Slovenia, is the largest city along the diminutive Slovene Riviera, or Slovenska obala, a sunny coastline packed with Adriatic allure. As soon as you stroll through Koper’s Muda Gate (a former town entrance), you’ll be treated to an explosion of Slovene architecture, art, zesty culinary staples, and vibrant neighborhoods humming with life. Slovenia’s picturesque seaboard clocks in at around 30 miles in length. The port city of Koper, situated along the northern reaches of Slovenia’s shores, is near the Italian border, and the Italian city of Trieste.
