Loup de mer grilled on a driftwood fire-yummy!
Hi, Beach camping is fine, just not fun anywhere north of Agadir.
If you want to beach camp to be alone, it’s pretty much impossible north of Agadir.
South, it’s a different story. There’s a piste that runs along the beach within the bird sanctuary just south of Agadir where you can chill. Further on places we have tested are a little piste that leaves from a well on the coast road, Foum Assaka, Plage Blanche, Foum El Oued Draa (good fishing near Ksar Tafnidilt), and then quite a few nameless beaches as you get towards and into the Western Sahara.
Just go, play it by ear. Some feel safe where others fear for their lives; I don’t know where you stand on that scale, so I can’t really say more. In Morocco I’ve only gone into campsites to empty the toilet, empty the rubbish, and fill up with water once a week if that. Otherwise we’ve always bivouacked, asking permission if/where there is someone to ask, and behaving modestly. We’ve never felt unwelcome, or potential targets; and further south you go the more welcoming the people become (further north i.e. Europe, the population is really very unwelcoming).
Beach fires: IMHO ships are not endangered by a fire on the beach, they have other nav means (GPS, radio beacons etc.) It’s more the small private fishing boats that you could confuse. You’ll probably want to light the fire on the lee (landward) side of the car anyway, the wind’s pretty constant on the Atlantic coast.
I would be opposed to beach fires because the use a resource already relatively rare in the region, that many locals use for cooking: wood. If you’re cooking, you’re no worse than a local, the desert will advance because of all of us. If it’s just to have a fire, beach party style, remember that the person (usually the woman) who must find wood for tomorrow’s cooking will have to walk further to find theirs after you’ve burnt what’s nearby.
Just my 2p (until the great day that Britain joins the euro)
