Reefs are a terrain feature in Civilization VI: Rise and Fall. Reefs are found exclusively on Coast tiles.


Reefs are an aquatic terrain feature found along the coastline. They block the construction of Harbors, Water Parks, and wonders, but are otherwise very valuable on their own. They increase the Civ6Food Food and Civ6Production Production potential of their tile and provide a Civ6StrengthIcon Combat Strength bonus to units defending there. They can also contain Fish (Civ6) Fish and Turtles (Civ6) Turtles and thus accept the Fishing Boats improvement, which makes them even more valuable.

After fully developing the Harbor of a nearby city, a Reef tile will yield +3 Civ6Food Food, +1 Civ6Production Production, and +5 Civ6Gold Gold, as well as +1 Civ6Science Science if you also have a Water Park with an Aquarium.

Reefs provide a +2 Civ6Science Science adjacency bonus for Campuses.

Civilopedia entryEdit

Reefs form beneath the surface of open water and serve as speedbumps for ships. Though some are composed of inorganic material such as sand, rock, or accumulated shipwrecks on reefs made of sand and rock, the most vibrant are coral reefs found in tropical waters.
