We walked to neck where the sea defence blocks are. The concrete blocks in the images below have been anti-tank blocks. Now they defend Spurn against the sea.
We arrived shortly after low tide and stayed until it was almost high tide. The rising tide was a stunning performance. The waves came in with enormous force to then collide with the blocks. Three days after full moon, this was a strong tide. - When we left after 6pm most of the blocks were submerged and the water level was still rising.
