Hi John,
Sorry, only see your post now.
I flew a few times around Galway a few years back.
Can't really remember where, but I think one slope I flew from was in the National Park I believe, and also along a few spots along the coast.
I'll try to find some photos of the places.
You can also contact the Galway Flying Club, they can be of help :
