What is the setting of this story? (Through the Tunnel) by Dorris Lessing

Lessing's depiction of the setting is characterized by a few vivid concrete details and many evocative emotional descriptions. At first, she describes the bay as "wild and rocky," then as "wild" and "wild-looking" in contrast to the "safe beach." The bay's wildness explains both the mother's concern and the boy's excitement. Later, as Jerry nears the bay, the reader is introduced to the bay as Jerry views it. Introducing the setting through Jerry's perspective primes the reader for the intense swim through the tunnel.
