In reply to Emma Reasbeck:
If it’s where I think it is then it looks about 6a-6b? The bolts are expansion bolts which aren’t great in the Sandy Mag-Lime the area has but I have no idea what size. The whole of Gorge Du Tarn was nearly de-equipped for expansion bolts pulling. If you go up, use caution.
p.S. don’t specifically mention the crag for access reasons
