Bus is the easiest way to get around most of Northern Israel, as the railroad currently only operates along the coast. However, work is currently underway to rebuild Jezreel Valley railway from Haifa to Beit She’an and construct a new line from Akko to Karmiel with the possibility of ultimately extending it to Kiryat Shemona. Bus service connects locations such as Haifa, Tiberias, Akko, Karmiel, and Kiryat Shemona with each other with high frequencies considering some of the population densities in these areas, and these cities also have their own internal services. Some routes connect these cities and others to places such as Tel Aviv, Jerusalem. However, other parts of Northern Israel, especially in the Golan Heights, are only served by a few buses a day if any at all.
