The walk along the rocky shore to Kettleness is dangerous unless the tide is carefully watched, and the road inland through Lythe village is not particularly interesting, so that one is tempted to use the railway, which cuts right through the intervening high ground by means of two tunnels. The first one is a mile long, and somewhere near the centre has a passage out to the cliffs, so that even if both ends of the tunnel collapsed there would be a way of escape. But this is small comfort when travelling from Kettleness, for the down gradient towards Sandsend is very steep, and in the darkness of the tunnel the train gets up a tremendous speed, bursting into the open just where a precipitous drop into the sea could be most easily accomplished.
