Bouldering near Ardennen

Hi,
I'm an English boulderer and I'll be staying in Ardennen for a family holiday in August. I'm looking for info about nearby bouldering.
From the map it looks as though there is some bouldering at Rocher Nasproue, but no details of how much or any more details.
Please does anyone have any info about this place or anywhere else nearby where I'll be able to boulder ?
Thanks in advance

You can download some topo's of small bouldering spots.
The largest is Izier. (Near Bomal). Went there once. Nice place. You can find boulders up to 7b. Don't forget to take a rope to work out some high balls.

Thanks very much for the link
