Frequently asked questions
How high does the Serra do Rio do Rastro climb?
To 1,460 m at its highest point, per the Santa Catarina Military Police page on the highway, with the steep wall section gaining most of that height in a short distance. The rim arrives suddenly: one moment you are in the switchbacks, the next on the plateau with the whole road below you.
Is the Serra do Rio do Rastro monitored?
Yes, permanently: the Military Police keep posts at the foot of the climb in Lauro Muller and at the top in Bom Jardim da Serra beside the viewpoint. For drivers that means help has fixed addresses at both ends of the hardest stretch, a reassurance most mountain roads cannot offer.
Where do you stop on the Serra do Rio do Rastro?
At the summit mirante, the viewpoint complex at the top with services, per the municipal tourism office. It is positioned exactly where a queasy passenger needs it, at the end of the wall, with the full sequence of hairpins laid out below. Break there in both directions if you are driving the serra twice.
When is the serra hardest to drive?
Afternoons, when fog rolls off the plateau and can cut visibility sharply; mornings are typically the clear window, which is why our tips put the climb early in the day. Fog on hairpins means creeping and braking, the jerkiest possible rhythm. If the top is already in cloud, wait it out below.
How many curves does the SC-390 climb have?
The number you will hear is 284, credited to the serra stretch in Brazilian media rather than pinned by an official measurement we can cite. What is beyond dispute is the shape: a near vertical wall of stacked hairpins, dense enough that the exact count hardly matters from the passenger seat.
What's the fastest way to stop car sickness mid-drive?
Once symptoms have started, pills won't work fast enough - they take 30+ minutes to kick in. The fastest options mid-drive are sound therapy via headphones (Dizzout states relief in about 90 seconds), pulling over for fresh air, and looking at the distant horizon.
