It’s pretty groomed and smooth tbh. Steady climbs and descents. Nicely twisty. OP is right its fantastic fun when dry and dusty – especially on a cross bike! The faster you go the better it gets. There is plenty of off peiste stuff leading off from it too.
IMO the red route is in pretty poor shape at the moment. Very washed out and tatty. If you know to find it the original red “rat run” is in much better shape if much shorter. I would keep kids off the red unless they are pretty able tbh.
