By Bus Or Taxi
Alternatively, you can take Egged buses from Tel Aviv 910, Jerusalem 940,960, Afula 301 or almost any city in the region to Haifa. During the Sabbath, you'll have to resort to a shared taxi sherut, most of which leave from near Tel Aviv's central bus station.
From Haifa the Hadar neighborhood, i.e. the uphill part of downtown, sheruts provide cheap frequent service to the cities of Akko, Nahariyya, and Karmiel, as well as to Haifa and its suburbs.
By plane
Haifa has its own airport, Haifa Airport which serves flights to Tel Aviv and Eilat, although the closest and only international airport is Ben Gurion International Airport in Tel Aviv, where flights arrive from all over the world. From Ben Gurion, you could connect on a flight to Haifa, although, chances are you'll have to transfer between terminals, or even airports, to Sde Dov Airport. The better option is to travel straight on to Haifa. It's less than two hours to drive, and buses, trains, taxis, and shuttles, operate on this route. The best way to get there from the airport is to take the train leaving from the airport terminal.
