Most of the trail goes near small towns, kibbutzim or places without a bank or ATMs. Here is a list, from north to south, of towns and cities on or very close to the INT, with banks and/or ATMs and the relevant map number from the guide (2009 edition). Most post offices have banking services but no cash machines.
