When determining a county’s coastal status in CK3, players often encounter inconsistencies. Some counties with coastline are not considered coastal, while others without coastline are. This inconsistency stems from the game’s mechanics, which define coastal counties as those with at least one coastal province.

From Chaos to Clarity: what is considered coastal ck3 holdings Simplified

To resolve this issue, players can use a coastal province map mode to identify all coastal provinces in the game. Once identified, players can check if a county contains any of these coastal provinces. If it does, then the county is considered coastal, regardless of whether it has an actual coastline.
