HU used to sponsor an event/ride in the Pyrenees called "HUMM". I think around Andorra? Not sure if it's still done? I never attended but read about it here. It was a sort of Poker Run routing contest.
On several rides in South of France I randomly ran into ongoing rallies. Usually in small, quaint towns. Wonderful!
One was in the Dorgodone region, another somewhere in Provence. I just showed up and was welcomed in! Food, Beer and LOTS of bikes.
Remember France has 5 times as many registered bikes as the UK.
These events were mid to late April, IIRC.
Check in with any good bike dealer in your area ... I'm sure they can hook you up with regional rallies and events. Check on line too, here and on French Adventure forums.
Lots of HUBB members from the UK (and EU) ride down to Morocco. I did it solo, but recommend going with riders who've been there before and know the routes.
I was reluctant to take off solo into areas I had no clue about. Watch here on the HUBB in Africa sections and route planning sections. I'm sure some rides
will come up.
If you haven't ridden around Spain, do take the time to explore. I spent a month there.
