Intercity bus is the
way most people come to Antakya (Hatay).
The city has direct bus service from
Ankara and several other cities, and
very frequent service from Adana, so
if you have any trouble finding a direct
bus to Antakya, just take any bus to
Adana, then change for a bus to Antakya.
From Antakya,
there's frequent service to the Syrian
border where
you can find other buses going to Aleppo
(Halep, Halab), Damascus (Dimashk,
Sam) and other points in Syria.
