How to plan the descent of Serra do Rio do Rastro safely

Considered one of the most beautiful and challenging roads in the world, Serra do Rio do Rastro, in Santa Catarina, attracts drivers and travelers in search of stunning landscapes and a unique driving experience. With its 284 winding curves and steep cliffs, planning is essential to ensure a safe and unforgettable trip. This practical guide explains how to plan your descent from Serra do Rio do Rastro, detailing the best times and essential safety tips to enjoy the journey without worries.

Best times and conditions for the descent

The success of your trip along the SC-390 directly depends on the weather and the time chosen. Visibility can change drastically in a matter of minutes, so prior preparation is essential.

• Best time of day: Early morning, just after sunrise, is usually the ideal time. At this time, heavy vehicle traffic is lower and there is a greater chance of finding the mountain with clear skies, providing spectacular views. Avoid late afternoon, when the shade can make it difficult to see the curves.
• Climatic conditions: Fog is the main risk factor. Before starting the descent, check the weather forecast and consult live cameras in the region. On days of intense rain or fog, the most prudent thing to do is to postpone the trip. Wet roads increase the risk of skidding.
• Best time of year: Spring and fall offer mild temperatures and a lower likelihood of extreme weather. Winter attracts tourists with the chance of snow, but it also increases the risk of ice on the piste (black piste) and temporary closures. Summer is marked by late afternoon rains, which can be dangerous.
• Traffic query: Always check highway conditions with the Santa Catarina Military Highway Police (PMRvSC) to find out about any traffic closures or restrictions.

Safety Tips and Stopping Points

Driving in Serra do Rio do Rastro requires full attention and a vehicle in perfect condition. Descent, in particular, puts stress on the braking system, making correct driving technique a crucial factor in safety.

1. Vehicle inspection: Before hitting the road, do a complete check-up. The most important item is the braking system. Check pads, discs and fluid. Tires that are calibrated and in good condition are also essential.
2. Use engine braking: This is the most important safety tip. Always get off with the car in gear (in first or second gear in manual vehicles, or in “L”, “1” or “2” mode in automatic vehicles). This helps control your speed without overheating your brakes.
3. Keep your distance and speed low: Drive down slowly, respecting the speed limits of the road. Keep a safe distance from the vehicle in front and never be in a hurry.
4. Do not exceed: The curves are tight and have no visibility. Overtaking is extremely dangerous and prohibited on most of the stretch.
5. Stop at the viewpoints: The main stopping point is the Mirante da Serra do Rio do Rastro, located at the top. In addition to offering an incredible panoramic view, it is a great opportunity to take photos and let the car’s brakes cool down before starting the descent. There are other pullouts along the route for quick stops.
