This is the high forest ride to build a trip around if you enjoy technical descending. The waterworks road offers a long contour across the mountain; the approach to Semkovo Hut then changes the mood completely, dropping through a steep, stony gully. **Ride:** climb to **Nehtenitsa**, turning left onto the waterworks road at **4.1 km**. Include the **Mochura** spur near **5 km**, then follow the contour west. Around **13 km**, the road becomes trail. At **14.1 km**, join the yellow/green-marked descent, and turn right towards **Semkovo Hut at 15.6 km**. Return east by road; at **18.9 km**, take the sharp left, cross the stream and climb. Leave the red markings right at **24 km**, continue through the **Toritsa area and Manovi Kolibi**, then join the asphalt at **30.5 km**. Turn right near **32.1 km** for the parking. The route runs **below Suhoto Lake**, without visiting its shore. Its singletrack lies in the national park and needs **prior coordination with the park Directorate**; a hiking waymark is not cycling permission. See the contact box at the end of this chapter. Choose snow-free summer conditions, carry lunch and take the final gully seriously. Semkovo Hut is a useful stop before the return leg. ## Before you set off Check weather and access, carry the map offline and leave your route and expected return with someone at Coliving. Match technical terrain to your riding skills. Check access restrictions before setting out.
