The English coastline re-emerges again in North West England. The coastline here is similar to the North Sea coast in that it is mainly flat and sandy, with the only notable cliffs along this stretch of coast being at St Bees Head in Cumbria. The English Irish Sea coast is an important area of estuaries and bird life, with Wirral being a peninsula bounded by two rivers, the River Dee and the River Mersey. Liverpool and Merseyside are areas of high population and important industry along this coast, with tourist resorts of Southport and Blackpool being further to the north.
