Since William Golding wrote his allegory in response to the theme of the Victorian novel, Coral Island, the island on which Ralph and the others find themselves appears to be a tropical paradise. The shoreline is "fledged with palm trees," some of which lean toward the light with feathery leaves as much as a hundred feet into the air. The ground around the palms is covered with coarse grass, which has been torn by the crash of the plane.
The island is about a mile from a coral reef which makes an arc that contains a lagoon whose water is still and all shades of blue and "shadowy green." Inside this lagoon the sand has been made into a bank by some storm or perhaps a typhoon, forming a deep pool in the beach with a high ledge of the pink granite. This The beach is narrow and endless; however, it is interrupted by a great plateau of pink grantie that runs up thorough the forest and sand and lagoon, forming a jetty four feet high. This area has only a thin layer of soil, rough grass, and smaller palm trees because there is not enough dirt for them to attain any size.
Farther up there are more rocks followed by a pink cliff that has another block of granite atop it, followed by still others. Throughout these rocks there are forest creepers that make climbing steep ascent to the mountain difficult. Feral pigs run through these creepers. Farther up, there is an open forest where the sea can be viewed and there is pink granite uncovered and unimpeded by creepers. Some of the rock is stack and piled like chimneys.
The island is somewhat shaped like a boat, the boys learn
...humped near this end behind them the jumbled descent to the shore. On either side ricks, cliffs, treetops and a steep slope: forward there, the length of the boat, a tamer descent, tree-clad, with hints of pink: then the jungly flat of the island, dense green, but drawn at the end to a pink tail.
This pink tail is a coral reef that encloses more than a half of the island. As the boys survey the island, they see beyond the falls and cliffs that there is a "gash visible in the trees," trunks have been splintered and then "the drag, leaving only a fringe of palm between the scar and the sea." The scar, of course, is where the plane has made its passage through the forest. As the boys scramble down the rocks, they encounter some dark green evergreens with many buds that resemble "candle buds." They descend toward the platform where they conduct meetings.
