You spawn on a plains headland at the edge of a deep lukewarm ocean, with savanna rolling away to the west. The prize is an Ancient City about 230 blocks to the southwest, with an Ocean Monument about 490 blocks north. Mushroom Fields sit about 510 blocks away across the water. Spawn itself is plain, and lush caves are absent.
