There were a few sign posts up in the car park indicating route we could have walked, and a rather helpful dot remarking 'You are here'. I nearly got out my pen and wrote alongside it 'But not where I want to be.' We chose to take the yellow route down the road marked 'American Road' which is known to us as 'The Tank Road'. Unlike the yellow line on the map it went on and on and on with no indication that was ever a right turn taking you out onto the grass and dunes. After a while we gave up and walked back again. The dog had had a good time.
A quick investigation along the blue path led me to the conclusion that it might have made a more interesting walk. But a lot of the burrows still looked be under flood water. Maybe I'll come back.
