Ocean is a base terrain in Civilization VI. It comprises all water tiles which are outside the shelf area, farther from land.

  • Base yields:
  • Impassable for sea travel before discovering Cartography


Ocean tiles, unlike Coast tiles, provide nothing for a city except Shipwreck Shipwrecks. Fortunately (since you cannot found a city in the water, like in the Rising Tide expansion for Sid Meier's Civilization: Beyond Earth), you usually won't need to worry about that, because you will have few or no Ocean tiles close enough for a city to work.

For all naval and embarked units, Oceans are impassible until the Cartography technology is researched (or for Norway, the Shipbuilding tech, and for the Māori, no tech). Thus, they present an insurmountable obstacle to early game exploration, and it is usual for different continents to remain separate (without contact with each other) until someone researches the necessary tech to sail in ocean. However, there is one other way to brave the open ocean: recruiting and retiring Leif Erikson, a Medieval Era Great Admiral, allows you to cross Oceans.

With Civilization VI: Gathering Storm, Seasteads can be constructed to improve these tiles.

Civilopedia entry[]

The deep waters of the oceans scared mankind for much of history, braved only by the likes of the Polynesians and Vikings. It took advanced sailing technology to brave these waters - and today, we fly across oceans in a matter of hours.
