You spawn in Plains at (8, -8), and the first real stop is a village about 269 blocks north-east, with a shipwreck about 228 blocks west and a ruined portal about 242 blocks south-east. The bigger prizes sit farther out: an Ancient City about 351 blocks north and an Ocean Monument about 386 blocks south-east. Cold Ocean covers about a fifth of the surrounding area, so expect plenty of water along the way.
