A range of tree-covered hills backstops the crash beach. Their most memorable appearance is probably during the pilot when the Oceanic 815 survivors first hear the Smoke Monster. (A layer of CGI trees was added in the foreground.)
The beach is quite narrow. Farrington Highway stretches along most of its length, with the slopes stretching skyward from its inland shoulder.
This valley between two of the hills is also recognizable in a few shots.
Finally, this shot looking back on the beach from the water gives a wider view of the hills.
