In reply to Obi Wan:
There is information in the Stone Country guide Boulder Scotland but no Topo as such.
Last time we were there the sand levels had all shifted and the river had re directed itself along the base!
In my opinion you'd be better off exploring the limitless possibilities on the hillsides above, all obvious from the road.Or walk for 10 minutes to find the in-obvious😊There are literally thousands of problems of all grades on superb rock that rarely needs more than a quick brush.All heights and type, just take a pad and wellies.Once the scale of the place is realised the difficulty of writing a guide becomes apparent!
Have a great trip!
