What does the environment look like in "The Most Dangerous Game"?

The natural setting of Richard Connell's "The Most Dangerous Game" is certainly forbidding.

When Sanger Rainsford falls off the yacht, he swims toward a screaming sound that he has heard in the darkness. For "an endless time he fought the sea," but he finally hears the water hitting a rocky shore. Rainsford pulls himself up the jagged rocks, and then he reaches a "flat place at the top." Touching the edge of the cliffs, he sees a dense jungle filled with a tangle of trees and underbrush.

Rainsford walks along the shoreline rather than struggle through the "web of weeds and trees." He follows this shore around a cliff until he sees lights on a high bluff where a palatial château rests. Around it on three sides are sheer cliffs that extend to the sea. Later, Rainsford learns that he is on Ship-Trap Island.
