From Ben Gurion Airport
1 hour by sherut (shared taxi) : 62 NIS (’12)
Sheruts depart from in front of the entrance of the 1st floor (ground floor).
45 mins – 1 hour by no.21 bus from Hebron Rd. 7.3 NIS (’12) *crossing a checkpoint
The bus stop is in front of EFFETA, a Christian school. It’s 20 mins walk from Manger square (where the Church of the Nativity is located). Though there is no timetable, the bus comes anyway.
However, the buses from Hebron Rd. take time because they make a detour to Beit Jala etc., and also the passengers are forced to get off at the checkpoint before getting into Jerusalem.
If you can go to the checkpoint between Bethlehem and Jerusalem by yourselves, it can be faster to take a bus from there (after passing checkpoint).
20 mins by bus no.21 from the checkpoint: 5.2 NIS (’12)
15 mins by private taxi from the checkpoint: about 40 NIS (’12)
Take care of taking legal taxis (yellow ones). White cars are illegal!
1 hour by bus no.18 from central bus station: 6.2 NIS (’08)
