Reefs form beneath the surface of open water and serve as speedbumps for ships. Reefs provide a +2 Science adjacency bonus for Campuses. They can also contain Fish and Turtles and thus accept the Fishing Boats improvement, which makes them even more valuable.Īfter fully developing the Harbor of a nearby city, a Reef tile will yield +3 Food, +1 Production, and +5 Gold, as well as +1 Science if you also have a Water Park with an Aquarium. They increase the Food and Production potential of their tile and provide a Combat Strength bonus to units defending there. They block the construction of Harbors, Water Parks, and wonders, but are otherwise very valuable on their own. Reefs are an aquatic terrain feature found along the coastline.
