Wadi Halfa is a location in 80 Days. It is situated in eastern Africa.
Wadi Halfa is a small settlement without a bank or a marketplace. It does however have a telegraph office, where Passepartout will meet several children tapping in morse code. If the player pays for each of the children to send their message, the telegraph office manager will reveal that their messages are mysteriously all the same; 'Ulundi Passepartout'.
The telegraph office can also be used to contact the editor of The Times on behalf of Henri de Blowitz.
