1. Plitvice Lakes National Park

As Croatia’s oldest and most visited national park, Plitvice Lakes deserves its reputation as a natural wonder. This UNESCO World Heritage site features a spectacular system of 16 interconnected lakes arranged in cascades and separated by natural travertine dams.

Essential Gear for Croatian National Parks: Versatile Hiking Boots
