A popular stop off is Asilah on the northern Atlantic coast (only about 40kms south from Tanger) - it is a typical beach resort (hotels etc) but has a nice old town too I understand...

You could stop there either on the way down or way back if you are sailing from Tanger. Depending on the time of your ferry - typically it's nicer to stay at Asilah the night/day before your sailing, and just drive up to the port in the morning?

Alternatively, if you had to get a later ferry on your way to Morocco, then perhaps head for Asilah that afternoon and then you could make Marrakech in a day from there?

Personally I would use Asilah as a stop off on the way back (just incase you are running short of time) - it would be a welcome rest before the big push back across Spain...

As for tracks and trails in Morocco - the place is riddled with them! Most of them (that are navigable by 4x4) are technically roads anyway, so you shouldn't be upsetting anyone (obviously as you say, if there are gates and signs, you should respect private property). However, a good number dead-end as they are primarily for access, or taper out to nothing more than a goat track or footpath.

The Michelin map (and others) shows many of the through routes, the GPS tracks from Olaf moreso - if you download the maps into Mapsource, you'll see a number of trails that aren't on the map, or are indeed through routes afterall etc.

Chris Scott's book has lots of piste routes in that you may also want to study while planning your route, but again - don't get hung up trying to do everything in one trip - it is a big place!

In just two weeks, you'll have more then enough of an adventure just sticking to the routes shown on 742 to be honest!
