You'll find excellent hospitality, views, and unspoilt areas in both Co Clare and Kerry.
Me and my family regularly go to see our cousins etc. in this area, and we never tire of the area.
Areas to call in at include KILKEE and KILRUSH, Clare. Try to get as far towards the west in Clare and Kerry to see the end of the River Shannon and the start of the Atlantic. There are some amazing views, aswell as great pubs!
These areas are a little cut off, so I'm not sure of the proximity of strips and airports, but Shannon is right in the middle of the two counties.
In Kerry, try to get to Dingle, a great little town, surrounded by the areas where "Ryan's Daughter" was filmed. Also great beaches and dolphin swimming out there if you like that kind of thing.
If you do manage to find an airstrip in the Dingle area, try to approach via the Connor Pass, it's a huge valley with great views from the ground, so aerial views must be excellent.
Have a great trip!
Regards
Mike
