The best available continuously ongoing coastal path and points of access to the coast along PRoWs can be viewed on an interactive aerial map (a Windows Live Map mashup).
There are 78 points of access shown on the map and they are numbered consecutively north to south. The average distance between access points is 1.8 km. Data relating the these access points and the sections of coast between them are on 8 Coastal Route Survey Forms.
The longest distance between access points is 11.6 km (65-66) on Sunk Island in the Humber estuary, and the next longest is 6.3 km (55-56) south of Withernsea. Although there is a de facto path along the 140-km coastline, only 86 km is along public rights of way. Except around Flamborough Head and along the Humber estuary, it is possible to walk for a total of 71 km along the shore except at high water. South of Bridlington, however, a coastal path along rights of way is missing from most of the coast, although it is possible to walk on the shore along almost the whole of its length. This situation is partly due to the rapid rate of erosion along this part of the coast that has created quite high (10-20 m) cliffs in the glacial till. The unstable and ephemeral nature of these cliffs makes access to the shore generally very difficult and, although we have not attempted to identify the points of access to the foreshore, they are probably less frequent than every 2 km. Restrictions to Cowden Parva (between points 39 and 40, map 3) are imposed by the MoD and there is running controversy about Hornsea bridleway No 1 (near 33). A description of the route and many photographs of the actual coast taken by David Cotton in October 2002 on his walk around the coastline of Great Britain, can be found at on the internet.
