Carretera CM-4157 is a very exciting journey through the heart of Montes de Toledo range, in Spain.
This scenic road is asphalted (bad condition) and pretty narrow. It’s 94.0 km long with hundreds of turns. It runs along the Cabañeros National Park.
The road links the towns of Guadisa (in the province of Badajoz, Extremadura N-502 road) and Navahermosa (in the province of Toledo and autonomous community of Castile-La Mancha CM-401 road).
