CTM is Morocco long distance bus service.

An additional long distance bus service in Morocco is Supratours, which is owned by the Rail network.
Both companies have a good safety and reliability record and are reccomended for travellers to Morocco.
Other companies do exist, however the comfort levels, security and safety records are often poor and so are not reccomended.
It is possible to travel from Tanger to Marrakech and the train timetables can be accessed by visiting http://www.oncf.ma
However, if you prefer to travel by bus from Tanger to Marrakech, you can travel with CTM.
CTM Bus station Tanger location
CTM buses in Tanger have an office and departure point convieniently located at the entrance to the Port.
To reach the office when you have arrived at Tanger port by ferry, walk from the ferry along the exit road to the entrance of the port. The walk should take about 4 or 5 minutes and unless you have heavy luggage, a taxi will not be required.
The entrance of the port is guarded by Police and has archways across the road.
Walk under the archway and the CTM bus station (effectively just an office) is located on the street corner immediately to your right, when standing facing away from the port entrance.

The CTM bus station office is just on the left of this photo.
