A cove is a small type of bay or coastal

creeks, or recesses in a coast
are often considered coves.

Colloquially, the term can be used to describe a sheltered bay. Geomorphology describes coves as precipitously walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. A cove can also refer to a corner, nook, or cranny, either in a river, road, or wall, especially where the wall meets the floor.

A notable example is Lulworth Cove on the Jurassic Coast in Dorset, England. To its west, a second cove, Stair Hole, is forming.

Formation

Map showing two examples of how coves form. The rock types are those of Lulworth Cove. In example A, a river breaks through the resistant chalk back rock and limestone, leaving the weak clays to be rapidly eroded. In example B, the sea breaks through the limestone, perhaps by forming a cave, and then erodes the clay away.

Coves are formed by

differential erosion
, which occurs when softer rocks are worn away faster than the harder rocks surrounding them. These rocks further erode to form a circular bay with a narrow entrance, called a cove.
