Croatia's diverse landscapes range from the rugged Dinaric Alps along the Bosnian border to the spectacular Adriatic coastline with over 1,200 islands. The coastal region features karst limestone formations, dramatic cliffs, and crystal-clear waters, while inland areas contain fertile river valleys like the Sava basin and the rolling hills of Slavonia. The Plitvice Lakes National Park showcases breathtaking travertine waterfalls and lakes, and the Istrian peninsula offers Mediterranean-style landscapes with olive groves and vineyards. The Velebit mountain range creates a dramatic backdrop to the coastal regions.
