Visited today (16 Feb), alongside a trip to Culross.
We parked in the layby but didn’t know about a gap in the fence so gained access via the north side of the bridge. A short slope took us to the underpass then we climbed a gate into the field. There were no cows on our visit, just lots of molehills and goose spoor.
The hero stone is striking, like an elegant clamshell, or frozen seaweed. There were small coins pressed into its deep and shallow cup- hollows.
One of the stones in the circle of three had a busy texture like wood or muscle fibres, a thick streak of quartz running down one side like fat.
We walked in the direction of the water then followed the fence uphill, past mature trees, including a few recently downed, probably by Storm Eowyn. We found the remains of an older wall in a copse.
Going a little uphill gets you away from the roar of the A985, and lets you see the stones in the context of the surrounding hills, and feel some atmosphere.
