Serra do Rio do Rastro, Mountain chain in Santa Catarina, Brazil.
Serra do Rio do Rastro is a mountain range in southeastern Santa Catarina that extends across densely forested slopes and high plateaus. The road SC-390 winds through the landscape, linking the coastal region to the higher plateau of the state.
The road through the range was built starting in 1903 to connect coastal areas with higher altitude regions of Santa Catarina. Construction took several decades and made trade easier between different climate zones of the state.
The name refers to the many streams that wind through the valleys and leave visible traces on the mountain slopes. Travelers often stop at viewpoints to photograph the serpentine road as it curves down the mountainside.
The mountain road requires careful driving, especially in winter when fog reduces visibility and temperatures may drop below freezing. It is best to drive during daylight hours in clear weather to navigate the many tight curves safely.
On very clear days, you can spot the ocean from the summit even though the coast is far away. Snow occasionally falls at higher elevations, a rarity in this part of Brazil.
