My god there actually is an island called Inaccessible Island! That's fantastic.

In that case, you will probably also be happy to learn about:

We have a mountain here called Bod an Deamhain meaning the Demon's D*ck. It has been anglicised into something more polite.

If you want something more bleak, there are also islands called Disappointment and Desolation.

This is the best thing, thank you.

Definitely on the short list of locations to build my Bond villain lair.
