National Park Sutjeska is the oldest and largest national park in Bosnia & Herzegovina, which is by its natural values and beauties the pearl of B&H and features one of the last remaining primeval forests in Europe. Tjentište in the Valley of Heroes is a home to the WW2 Battle of Sutjeska memorial complex.
Straight out of Trebinje, you’re greeted with a 6 km climb @ 5 % and then, after some rolling terrain along side a large artificial lake, you gradually continue climbing for the next 50 km as well! A short downhill section to catch your breath will be handy because the beauty of the National Park will take it away again. You’ll be able to enjoy it over a full lunch though, so you’ll be glad to reach CP6 in more ways than one, especially as it marks the half-way of the whole route and your personal battle!
