Probably about 20 problems possible including an excellent traverse above a bowling green landing (though moist)
Its location is hard to see on google maps but its in the vicinity of the below co-ords
I also heard there was some bouldering in the col beneath the summit of Heckla ? south uists highest peak but i never made the journey.
If you make it across to Barra there is a great boulder at Clac Mhor Nan Glennan which overlooks the airport/beach.
Best of all though is Aird Mhinge on Harris lots to do and lots to discover in the area (topo on scottish climbs)
