Chancer, "trip and falls" on footpaths or roads is a different part of the legal code altogether and doesn't provide guidance for just how quiet the area of law you were talking about has gone. Walking around Irelands Eye is done at your own risk, period.
Now, you do pay money to the boatman, so accidents while "landing on an island without a proper landing stage" is slightly more fertile ground, but the target is the boatman, not the island.
Look, there is of course a degree of subjectivity involved, but lets say that if a slide in a children's playground hurts a child, that is the other end of the spectrum altogether to falling over a rabbit hole on Ireland's Eye.
The good old days (OK, a subjective comment, I admit) are gone forever.
Owners of wild islands can sleep perfectly well at night these days (as it were).
