This question consists of two parts:
Is it possible to walk from Ceuta to Tanger Med along the coast?
There seem to be roads and/or beaches along some of the Moroccan coastline, but not all of it – are there any continuous paths at or near the rest of the coastline?
Is the Trains navettes rapides line between Tanger Med and Tanger Ville in operation?
The rail line is included in the official railway map, yet there are no schedules for it on the ONCF website and the ONCF trip planner shows no connections between Tanger Med and Tanger Ville despite knowing both stations.
