It passes through the spa town of Dolna Banya and the villages of Maritsa and Raduil and ascends to the Borovets ski resort (1,335 m)[2] in the northern slopes of the highest mountain range in the Balkans, Rila.

From Borovets the II-82 descends to the Samokov Valley to the north along the river Musalenska Bistritsa, runs through the homonymous town[2] in direction south–north and after exiting the valley enters the short Kalkovo Gorge on the river Iskar at the latter's confluence with the Palakaria.

Then, for 11 km it runs parallel to the western shores of the Iskar Reservoir, the largest in Bulgaria.

Downstream from the dam, in the vicinity of the village of Dolni Pasarel, the road enters the 22 km Pancharevo Gorge between the mountain ranges of Vitosha and Plana to the west and Lozen Mountain of Sredna Gora to the east.

[2] In the center of Samokov, it intersects with the eastern terminus of the second class II-62 road Kyustendil–Dupnitsa–Samokov.
