It's a few years since we last visited MStM,
('maybe 10' turns out it is 14!),
but there was a permanent causeway linking it to the mainland
and extensive hardened parking.
This wiki article details the project to flush silt out of the bay
and return MStM to an island,
with parking on the mainland.
In an uncharacteristic feat of memory, I remembered that it was Noirmoutier I had in mind. I have a hazy recollection of my parents having to hose saltwater off the wheels so the car didn’t corrode.
