A cove is a small, sheltered part of an ocean's coast. A cove can be a good place to put a sea kayak in the water and start paddling along the shore.
A cove is basically the same thing as a "bay," but smaller. Coves are protected coastal areas affected by tides and connected to the open sea by a narrow entrance. The water in a cove is calmer than the open ocean, and the cove itself is often oval or circular in shape. The earliest meaning of cove was "den or cave," and later "small bay," probably influenced by a Scottish meaning of the word, "hollow place in coastal rocks."
