The ocean monument sits about 520 blocks west of spawn, and a shipwreck lies about 466 blocks west, so the sea route is worth the trip. Spawn is in Snowy Plains on a peninsula, with open water within about 400 blocks on nearly every side. An igloo stands about 47 blocks south-west and a ruined portal about 72 blocks south, so you can start gearing up before heading west.
