This section of the Forest Trail leads through the entire Gauja National Park and gives an opportunity to see all the most beautiful places and sights of this national park of more than 100 km. Gauja National Park is the oldest and largest national park in Latvia. The ancient valley of the River Gauja is the deepest river valley in the Baltic states. The banks of the River Gauja reveal colourful sandstone outcrops, which are reflected in the water. The sights are most wonderful in springtime, when bird cherry trees are in full bloom, and in autumn, as the trees turn red and yellow. The ancient valley of the River Gauja has a distinctive terrain relief that can fluctuate by up to 80 m. The largest part of the road leads through forest paths, along the river, and exits the woods in Līgatne and Sigulda.
Almost half of the park is covered by forest. Gauja National Park is known for the great diversity of specially protected forests, featuring herbaceous spruce forests, slope and ravine forests, as well as mixed broadleaf forests.
