The walkers cross over Portland
Island and now look out over the western coast. Below is Chesil
Beach. It is a pebble beach 18 miles long and stretches north-west
from Portland to West Bay. For much of its length it is separated
from the mainland by an area of saline water called the Fleet
Lagoon. Prior to the road being built to Weymouth it was the only
way to leave the island by foot. This beach was the grave of
many sailing ships trapped by the prevailing SW winds.
