PARC NATIONAL DE LA DRINA

This national park covers 63 ^km2, stretching 40 km along the west bank of the Drina from Lake Perućac in the east. V-shaped, it hugs the protruding part of Serbia, which is home to Tara National Park. It remains poorly developed, with few signposted trails and no roads to cross it. The canyon is 11 km long and with walls over 900 m high, it is considered the third deepest canyon in the world after the Colorado (USA) and the Tara (Montenegro).

Bosnian hamlets and Serbian spruce. Throughout the park, the steep terrain makes for long journeys, with peaks such as the Ljutica (1,238 m) and Luceva Ravan (1,146 m) mountains to the north, and the Stijene (1,244) and Sanik (1,237) mountains to the west. There are Bosnian-populated hamlets such as Međe (pop. 60), Klotjevac (pop. 40) and Luka (pop. 60). But the local police now forbid residents to rebuild their homes destroyed during the 1992-1995 war, on the pretext of preserving the park. On the banks of the Drina, near Klotjevac, a makeshift campsite hosts a summer "peace camp" in memory of the Srebrenica genocide. The forests are mainly composed of black pine, beech and oak. There is also the Serbian spruce, an endemic species of the Tertiary era, found mainly in the western part of the park. Some very rare flowers, such as the Derventa knapweed, grow only in the region.
