Not much traffic, pretty flat but winding, okay asphalt in the south but pretty bad in places in the north (iirc it got asphalt around 1980 and I’m not sure if it has ever been repaved since...), in the north end you can continue on pretty roadbike-friendly gravel in either direction.
(Kollasentie is paved all the way to the primary road as well, but then you have nowhere nice to go from there).
