I've read somebody's comment from 2008 about and there is told
"Although very narrow two-way street. No part paved, stones rolling down the entire length hundred meters high cliffs with no safety railings without safety bays. No doubt the views are crazy, but with fear because of the trip on the precipice not possible to enjoy the view. All travel time can not pass the 20 km /h, very dangerous!
Do yourself a favor you're on vacation, go do Bungee jumping. Its much more safer."
