A pier is a structure built over water, often extending from the shore into a lake, river, or ocean. It is typically made of wood or concrete and serves various purposes, such as providing a place for boats to dock or for people to fish. Many piers also have walkways where visitors can enjoy scenic views and fresh air. In addition to their practical uses, piers are popular spots for recreational activities. Families often visit piers to enjoy a day by the water, while fishermen may cast their lines hoping to catch fish like trout or salmon. Some piers even feature shops and restaurants, making them lively destinations.
