The yellow double center lines indicate right-hand traffic. The rugged, steep rock face and the lush, temperate vegetation suggest a mountainous region in a tropical or subtropical country. The orange plastic barriers are typical for road construction or event management in Latin America. Given the terrain and the cycling culture, this looks like a high-altitude road in the Colombian Andes. I suspect this is near Bogotá, Colombia.

I am 60% sure.

The presence of many cyclists on a steep, winding mountain road is iconic for the climbs leading into Bogotá, such as the Alto de Patios or the road to Choachí. The specific rock formation and the lush, damp vegetation are very characteristic of the Eastern Cordillera of the Colombian Andes. The road markings and the orange barriers are consistent with typical Colombian road infrastructure. I am confident this is in the mountains surrounding Bogotá, Colombia.

I am 85% sure.
