Sri Lanka is an island nation in the Indian Ocean, set just off the south-eastern tip of India like a teardrop hanging from the subcontinent. Only a narrow band of shallow sea, the Palk Strait and the Gulf of Mannar, separates the two, and at its closest the island lies barely 30 kilometres from the Indian mainland. If you want the short answer: Sri Lanka sits in South Asia, in the northern Indian Ocean, alone in the sea with no land borders and open water on every side.
For most of its recorded history the island was known to the outside world by other names, Ceylon to the British, Serendib to Arab traders, Taprobane to the ancient Greeks and Romans. Whatever it was called, its position at the centre of the Indian Ocean has always defined it: a natural stepping-stone on the sea routes between East and West.
Where is Sri Lanka on the map?
Sri Lanka lies between roughly 6 and 10 degrees north of the equator and 80 to 82 degrees east, which places it firmly in the tropics, closer to the equator than almost anywhere in India. The nearest point of the Indian mainland is the state of Tamil Nadu to the north-west; beyond the surrounding ocean, the Maldives lie some 700 kilometres to the south-west, and the vast expanse of the Indian Ocean stretches uninterrupted all the way to Antarctica in the south.
The island is compact and roughly pear-shaped: broad across the centre and north, then narrowing to a single southern point at Dondra Head, the most southerly tip of the whole country. From the cultural cities of the interior to the beaches of the coast, nowhere in Sri Lanka is very far from the sea.
Because it stands alone in the ocean, Sri Lanka has no land borders, a rarity that has shaped its history, giving it both the protection of the sea and a long tradition of maritime contact. The waters around it each have their own name: the Palk Strait and Palk Bay to the north-west, the Gulf of Mannar to the west, the broad Bay of Bengal reaching away to the north-east, and the Laccadive Sea, part of the wider Indian Ocean, washing the southern and western shores. Sitting so near the equator, the island also lies squarely within the path of the monsoons, the seasonal winds that sweep in from the ocean and, more than anything, govern its climate and its best time to visit.
How close is Sri Lanka to India?
Remarkably close. The Palk Strait, the stretch of sea dividing the island from the Indian mainland, narrows to only about 30 kilometres at its tightest point, between Talaimannar on Sri Lanka’s north-western Mannar peninsula and Dhanushkodi on India’s Rameswaram Island. Across this gap runs one of the most storied features in the region: Adam’s Bridge, a 48-kilometre chain of low sandbanks, reefs and shoals, known in the Ramayana tradition as Ram Setu, “Rama’s Bridge”. That very nearly links the two shores. For much of history parts of it were shallow enough to wade across at low tide, and it still keeps large ships out of the strait, which is why most vessels take the long way round the island.
Despite this closeness, there is no land connection and, at present, no ferry or bridge in regular service. The short sea gap has, however, shaped everything from ancient migration and the spread of Buddhism to the modern story of the island. You can read more in our history of the ancient kingdoms and the arrival of Buddhism.
How big is Sri Lanka?
Sri Lanka is a small country, but bigger than many first-time visitors expect. It covers about 65,610 square kilometres (25,330 square miles), a shade smaller than the Republic of Ireland, roughly the size of the US state of West Virginia, and comparable to Lithuania or the Australian island of Tasmania. It stretches around 432 kilometres from its northern tip at Point Pedro down to Dondra Head in the south, and reaches about 224 kilometres at its widest from east to west.
That modest scale is one of the island’s great pleasures for travellers. Within a compact area you can move from tropical beaches to misty tea country, from ancient ruined cities to national parks full of elephants and leopards, without ever travelling far. The catch is the terrain and the roads: the central hill country rises steeply to Pidurutalagala, the highest peak at 2,524 metres, and mountain routes are slow and winding, so journeys often take longer than the map suggests.

A crossroads of the Indian Ocean
Look at Sri Lanka’s position on a world map and its historical importance becomes obvious. The island sits astride the great east–west shipping lanes of the Indian Ocean, the sea highway that has carried goods between the Middle East, India, South-East Asia and China for millennia. Ships sailing between the Suez Canal and the Strait of Malacca still pass close by its southern coast, one of the busiest maritime corridors on earth.
This location made Sri Lanka a natural trading hub long before the colonial era. Arab, Persian, Chinese, Roman and later Portuguese, Dutch and British traders all called here for cinnamon, gems and elephants, and the island’s great natural harbours, Colombo on the west coast, the historic port of Galle in the south, and the deep-water anchorage of Trincomalee in the east, became prizes fought over by successive empires. That legacy of exchange is written into the island’s food, faiths and languages to this day, as our pages on Sri Lanka’s people and religion explore.
Getting there and getting oriented
For nearly all visitors, arriving in Sri Lanka means a flight. The main gateway is Bandaranaike International Airport (CMB) near Colombo on the west coast, with a smaller international airport at Mattala in the south. There are no scheduled passenger ferries from India at the time of writing, so despite the two countries’ closeness, air travel is the practical route in, see our guide to getting to Sri Lanka for the details.
Once you have your bearings, the island falls into a handful of natural regions: the busy west coast around Colombo; the cultural heartland of the hill country around Kandy and Ella; the ancient Cultural Triangle in the north-central plains around Sigiriya; the historic southern coast by Galle; and the wildlife-rich dry zone of the south-east around Yala.
