Littlehampton Harbour sits at the mouth of the River Arun on the West Sussex coast, where river and sea meet in a lively blend of maritime activity.

A busy small port serving both as a working harbour for commercial vessels and fishing boats, and as a popular destination for leisure craft, paddleboarders, and visitors exploring the waterfront. With its picturesque landscape, lifeboat station, and easy access to the English Channel, the harbour has long been a focal point of the towns identity. Today, it combines heritage and modern uses supporting marine industries while offering scenic walks,  and views out to sea.
