Hi ally,
The Benone complex is the nearest to Limavady.
I don't like it though. Its too far away from anything, theres not much there and its far too big.
Is there a particular reason for going to Limavady? Friends or family maybe?
If not, then try Ballyness in Bushmills, Drumaheglis in Ballymoney, Bellemont near Portrush (or going further afield Delamont C&CC site in Downpatrick). They are all great sites, well maintained, clean and not too big.
Have a browse on the discovernorthernireland website then post a choice or two and I'll give you an honest critique.
In the end it all depands what you're looking for. Is it peace and quiet and a nice view, or plenty to do?
