Located in the Smolyan Province of Bulgaria, Devil’s Throat Cave (Dyavolsko garlo Cave) is the name of a spectacular cave resembling a devil's head with a waterfall rushing down its throat. Oncoming traffic is a nightmare. The road is cut into the rocky side of the gorge.
Buynovo Gorge road is located in the Rhodope Mountains, north of the village of Buynovo (Borino municipality), on both sides of the Buynovska River which is a tributary of the Vacha River, Bulgaria. It is recommended that beginner riders avoid this road. There are sheer drops virtually along the entire route and enough hairpins to make a whirling dervish dizzy.
