I had been hoping to drive across North Africa from west to east, but the obvious border problems, plus the costs of traveling through Algeria, Libya and Egypt with my own vehicle means I'm having to change my plans.

I want to try and "follow" the prime meridian from London to the coast of Ghana. Not following it completely, but visiting places along the way that sit on (or are very close to) the prime meridian.

My main problem is Algeria.

Are there any ferries from europe to Algeria currently running at all.

If so then I can either land in Algeria, drive down to Ghana and back up to Europe via Morocco, or do the reverse; landing in morocco and driving down to Ghana before returning to europe via Algeria.

If there are no ferries, then my only choice is to drive down via morocco, visit Mali, Burkina and Ghana before crossing the southern border into Algeria and then exit Algeria so I can drive back up to europe via morocco again.

So, the prime meridian passes through the west of Algeria, from Mostaganem on the coast to Bordj Mokhtar on the southern border, anyone have any knowledge of these area's or anywhere else well worth visiting within Algeria that sit close to the prime meridian.

Also, does anyone knows wether the confluence of the prime meridian and the tropic of cancer is accessible at all?

Thanks guys!
