Creepy Island related to St Patrick

Obrienc

Folks
I am looking for some information on a story related to st patrick.
I heard this story on youtube. it was a voice interview with an irish man.. I cannot for the life of me find it now.... and Id love to look into it.

The story relates to how there is an island (somewhere in the north of ireland I think) that is somehow spilt in two... what I mean by this is that the west half of the island feels good, nice etc, and the east side feels creepy and evil... its an old story that I am wondering if anyone has any information on

when it was told , it was related somehow to the banishing of snakes.... that this is where they were sent or something along those lines?

Note this is not the story related to the old cave on station island... I am aware of that story....

any information is appreciated..

thanks
C.

saints island sounds like. It had a cave where pre christians would meditate - became a cave where apparently st patrick encountered purgatory which now is that money spinner on Station Island in Donegal. This is about it:

saints island is also split in two by two distinct types of vegetation. You'll need permission to go there though (i have photos somewhere of the vegetation)

Outlined in this (including the 'split in two' bit)
