When it comes to maritime transportation and trade, natural harbours play a crucial role. These sheltered bodies of water, protected from the open sea by natural structures like bays, inlets, and headlands, provide ideal locations for major cities and serve as important gateways for ships to dock. In this article, we will explore the ten largest natural ports in the world, highlighting their features, historical significance, and economic impact.
Port Jackson/Sydney Harbour, Australia
There is no natural harbor in the world that is bigger or deeper than Port Jackson, which is also called Sydney Harbour.Located in New South Wales, Australia, it covers an area of 55 square kilometres and stretches for 19 kilometres. The irregular foreshores of Port Jackson extend for over 150 miles, providing extensive docking facilities for ships.
The entrance to Port Jackson is flanked by the North and South Heads, which are home to naval and military stations. The Sydney Opera House, Sydney Harbour Bridge, and the rest of this famous harbour are world-famous attractions in addition to the stunning scenery.
Port Jackson serves as the principal port facility of New South Wales, handling a variety of cargo, such as petroleum products, dry bulk, containers, and general cargo. Annually, approximately 29.2 million tonnes of cargo, including 1.8 million TEUs (Twenty-foot Equivalent Units), are handled at this bustling port.
Historical Significance
Port Jackson, commonly known as Sydney Harbour, holds immense historical importance for Australia. It was the first place where Europeans lived in Australia. They came in 1788 with Captain Arthur Phillip’s First Fleet. This was the start of British settlement and the building blocks of modern Australia. The harbor has since played a crucial role in the development of Sydney and the nation as a whole, serving as a major port, naval base, and iconic landmark.
Key Features and Statistics
- Area: Approximately 55 square kilometers (21 square miles)
- Shoreline: About 317 kilometers (197 miles) in length
- Depth: Varies, with an average depth of 13 meters (43 feet)

- Annual vessel movements: Over 40,000 commercial and recreational vessels
- Economic impact: Contributes significantly to tourism and trade, with the Port of Sydney handling over $60 billion in trade annually
Unique Feature
One of the most unique features of Sydney Harbour is its natural “drowned river valley” formation. Unlike many other harbors that are artificially created or heavily modified, Sydney Harbour was formed when rising sea levels flooded the Parramatta River valley at the end of the last ice age, around 10,000 years ago. This geological history has resulted in a complex system of bays, coves, and inlets, creating a naturally deep harbor with numerous sheltered anchorages. This unique topography not only makes it one of the world’s most beautiful natural harbors but also contributed to its historical importance as a safe haven for ships and its ongoing significance as a major port.
Poole Harbour, United Kingdom
Poole Harbour, situated in Dorset, England, is the second-largest natural harbour in the world.Formed at the last glacial period, this harbour is one of a kind; it is an estuary for multiple rivers, the biggest of which is the Frome River. With an average depth of 48 cm, Poole Harbour covers an area of approximately 36 square kilometres.
The shallow nature of Poole Harbour requires careful navigation through dredged channels. Marinas line its shores, making it an ideal spot for leisure sailing and boating. Fishing, cargo handling, ship repair, and oil rig lay are just a few of the many industries that rely heavily on the harbour.
Poole Harbour handles a diverse range of cargo, including Roll-on/Roll-off (RORO), bulk, chemicals, and private quays for sea-dredged sand, timber, and petroleum products. Annually, around 1.13 million tonnes of cargo and over 4,000 TEUs are handled at this vibrant harbour.
Historical Significance
Poole Harbour has a rich history dating back to prehistoric times. It was an important trading port during the Roman occupation of Britain and continued to be a significant maritime center throughout the medieval period. The harbor was very important during World War II because it was one of the main places where ships left for the 1944 D-Day attacks. Its strategic importance and natural features have made it a key site for maritime activities, trade, and defense for centuries.
Key Features and Statistics
- Area: Approximately 36 square kilometers (14 square miles)

- Economic impact: Significant contributor to local economy through tourism, fishing, and commercial shipping
Unique Feature
A unique feature of Poole Harbour is its double high tide. This rare tidal phenomenon results in two high tides in quick succession, with only a slight drop in water level between them. This occurs due to the harbor’s unusual shape and its interaction with the tides of the English Channel. The double high tide extends the period of high water in the harbor, which has historically been beneficial for maritime activities and continues to influence the harbor’s use today. This feature, combined with the harbor’s shallow nature and numerous islands, creates a complex and ecologically rich environment that is rare in the UK and globally.

Comment(01)
Greetings –
Despite lots of excellent factual information, this article includes some ridiculous claims – partly because it confuses”ports” with “harbours”. For example, Rotterdam is Europe’s busiest port, but is clearly not a “natural port”, i.e. a naturally-enclosed harbour. The claim that Port Jackson/Sydney Harbour is the world’s “biggest natural harbour” is equally ludicrous; I refer you to Australia’s busiest port, Port Phillip – a natural harbour with a surface area of 1930 sq.km., compared with Port Jackson ‘s puny 55 sq. km. And to include in this list the muddy inlet of Poole Harbour, unable to accommodate ships of any size, is really stretching your readers’ sense of humour.
