On one forum I read a post saying the best way they had found to get from UK to Kyrenia was to fly to Larnaca and then take a taxi to the North. If so then the possibilities of travelling North/South are a lot more fluid than when I was there in 2004. If you are going to Bella Pais be sure to read Lawrence Durrell's "Bitter Lemons" - set mostly in the village. He tells a wonderful proverb about Cyprus:
The most idle people in all the Mediterranean are those that live in Cyprus;
And the most idle people of all Cyprus are those that live in Bella Pais;
And the most idle people in Bella Pais are those that sit under the Tree of Idleness.
So, of course, Hilary and I had to sit under this tree (it had a bar/retaurant built around it) and enjoy an Efes after touring the splendid Abbey.
