The Point Abino thing has been a thorn in the side of Canadians for a long time.
A whole freakin peninsula privately owned by Americans with their million dollar "cottages" on it, with public property at the end, that they make insanely difficult to access. They "allow" a few busses a year for organized tours for which they soak the organizers thousands of dollars per year. They'll begrudgingly let you walk but you need to sign a legal document saying you do so at your own risk and peril.
But cars....GTFO. Unless of course you're an emergency vehicle or something in the case of an emergency, then hey, come on in, no problem.
It's been contentious for years and there's been more than a few plans to expropriate the road to allow the public to access to the lighthouse, but it never seems to happen.
Go by boat??
