I have been to Israel 5 times and plant to visit this month and rent a car for the first time. I want to drive up to Isfiya on Mt. Carmel. I read the road is narrow with some pot holes and am concerned with taking a rental car up there. What is the most direct and safest way from Nazareth Illit to Isfiya? Will I have enough room if I meet a bus on the road up to Isfiya?
