Hi,
Been there lots of times but never noticed the possibilities of a big dune.
It's at Barley Cove at the very end of the Mizen Peninsula.
Map from Google Earth
If you are down this way, just head SW from Skibbereen towards Crookhaven and follow the signs to Barley Cove.
There's a short walk from the car park, but it's easy on a boardwalk.
There's absolutely loads of space to land, grass and sand.
And there's a huge beach for the wife/kids to play on too.
My guess is it will only work in a southerly wind.
Haven't tried it yet, but will report a.s.a.p. when I do.
