Hansjorg Voth's 3 scupltures to the north are well worth a visit. The route I took wouldn't be that good for a saxo but the way back would
City of Orion N31 36.783 W4 31.538
Stairway to Heaven N31 34.890 W4 28.720
Golden Spiral N31 35.505 W4 32.099
Piste Start (Shown In Olaf) N31 31.819 W4 29.447
The ealier turn off at N31 31.638 W4 27.967 involved a muddy river crossing and some baby dunes last December
There is a Guardian and your supposed to book but I just rocked up and git caught by him at the City of Orion. I think the visit fee iss 200dH but could be wrong I recall thinking it was expensive. Worth the cost as he'll show you the insides.
Worth noting that the guardian and cost is apparently due to damage caused by overland groups. (surely not any respectable HUBB users though
