The gate is occasionally open, that being said this area is dangerous for rock slides and has a history of major geological instability. There is debris and rockfall from the cliffs above on to the road. It is in fact drivable many KM up, but it is officially closed and a fine of several hundred dollars could be issued if caught by a warden etc
Yeah I know.. gravel bike or mountain bike can make quick travel here. I always worry if there's big rock fall and you get trapped up there with a car, a bike might offer a little more flexibility?
