Seems to be a theme here of wild and windblown places. Northern Ireland isn't quite so high or red in tooth and claw as some of the places you mention. It is, however, relatively free of crowds once you get out of the cities. Three decades of trouble means we don't get the crowds that some parts of the Republic get (I hear that there was some consternation on the ring of Kerry down south last year as people in motorhomes have started using GPS to navigate. In Kerry the quick way is not the way to go - you have to follow the signs that the locals have put up otherwise it ends up in gridlock !).
Two places I love are less than an hour and a half from Belfast - Fermanagh and the Glens of Antrim.
Fermanagh has wonderful Lough Erne with hundreds of islands, the best fishing in Europe outside of Northern Sweden and thousands of years of history to discover. Here's a fishing map

If you look at the southern shore of the lower Lough you'll see a green area called Navar. Drive up there late on a summer evening and watch the sun dip red into the golden atlantic ( next stop New Foundland ?), You'll see the Hills of Donegal, the Erne flowing to the ocean, the Sligo Mountains and the Lough itself laid out like this map below you.
The Glens of Antrim is somewhere you are not allowed to visit. We already have sufficient tourist to this glorious landscape. Each of the Glens have their own story reaching back into pre-history, each of them is a jewel. See for yourself - http://www.northantrim.com/theglensofantrim.htm .
From Torr Head you can see Upyerkilt in Scotland and half the Hebrides including the Paps of Jura.
Somewhere you are not allow to visit under pain of a hangover is Johnny Joe's in Cushendall - wonderful real ( yes, real - not a phony-franchise ) Irish pub with sessions on Thursdays, Fridays and Saturdays. Check out the village - http://www.northantrim.com/cushendall.htm .
I could tell you how beautiful Layde Church is, but I won't ;
