40 free UK Geography trivia questions with answers — geography quiz, new questions added Aug 2026.
The United Kingdom packs a lot of geography into a small space: four nations, a capital that only became one in 1955, a loch holding more water than every lake in England and Wales combined, and a 335-year war with the Netherlands that nobody noticed. Most of us can name the longest river and the highest mountain, and then the certainty runs out. These 40 questions run from the four capitals and the big rivers through the national parks, lakes and islands to the coastline, the counties and cities, the motorways and the record-holders: the most southerly and northerly points of the mainland, the lowest land, the village farthest from the sea, the smallest city and the smallest county. Every answer comes with a one-line explanation that adds the detail the textbook leaves out. Play it as a quick British geography test, use it for a pub quiz round, or print it for a classroom.

Q 01Which river, Britain's longest at 220 miles, rises on Plynlimon in Wales and flows past Worcester and Gloucester?
Severn
The Severn has a tidal bore: on big spring tides a wave runs upstream past Sharpness, and the water level keeps rising for about an hour and a half after it passes.
Q 02Which river is called the Isis where it flows through Oxford, before passing Windsor and London on its way to the sea?
Thames
The Thames is the Isis at Oxford because Victorian mapmakers insisted the whole river kept that name down to Dorchester, where it meets the Thame to become the 'Thame-isis'.
Q 03Which Scottish mountain, 1,345 m high, carries the ruins of a weather observatory that was staffed from 1883 to 1904?
Ben Nevis
Ben Nevis was only confirmed as Britain's highest mountain in 1847, ahead of its rival Ben Macdui, and a stint at its summit observatory inspired C. T. R. Wilson to invent the cloud chamber.
Q 04Which Scottish lake, 230 m deep, holds more water than every lake in England and Wales combined?
Loch Ness
Loch Ness is only the second-largest Scottish loch by surface area, behind Loch Lomond, yet its depth makes it the largest body of fresh water by volume in the British Isles.
Q 05Which city, granted city status in 1905, was proclaimed the capital of Wales only in 1955?
Cardiff
Cardiff became capital through a Commons answer by Home Secretary Gwilym Lloyd George, and the Encyclopedia of Wales says the choice owed more to its marginal Conservative seats than to any reasoned view of a capital's role.
Q 06Which city, at the mouth of the River Lagan, launched the Titanic from its Harland & Wolff shipyard in 1911?
Belfast
Belfast's Titanic was the largest ship afloat when launched, and Harland & Wolff, the yard that built her, employed around 35,000 people at its Second World War peak.
Q 07Which Scottish city, said like Rome to sit on seven hills, has a castle perched on the plug of an extinct volcano?
Edinburgh
Edinburgh's Arthur's Seat is the eroded remains of a Carboniferous volcano, and the city's Fringe has grown into the world's largest performing arts festival.
Q 08Which 978 m mountain, the highest in England, had its summit given to the National Trust in 1919 as a war memorial?
Scafell Pike
Scafell Pike's summit was donated by Lord Leconfield in memory of local men killed in the First World War, and over 100,000 people a year now climb it from Wasdale Head.
Q 09Which Welsh mountain, the highest in Britain outside Scotland, has had a rack railway to its summit since 1896?
Snowdon
Snowdon's line is the only public rack-and-pinion railway in the UK, and since 2022 the national park authority has used only the Welsh name, Yr Wyddfa, for the mountain.
Q 10Which ribbon lake in Cumbria, about 11 miles long, is the largest lake in England by length, area and volume?
Windermere
Windermere already ends in 'mere', Old English for lake, so 'Lake Windermere' says lake twice; Sir Henry Segrave set a world water speed record on it in 1930.
Q 11Which river, tidal below Perth and reaching the sea at Dundee, has the largest measured discharge of any in the UK?
Tay
The Tay also holds the British salmon record, a 64 lb fish landed by Georgina Ballantine in 1922, and in January 1993 it rose 6.48 m above normal at Perth, flooding the city.
Q 12Which 97-mile river, flowing past Peebles, Melrose and Kelso, forms 19 miles of the border between England and Scotland?
Tweed
Tweed may come from an Old Brittonic word meaning 'border', and only 7 km of its course lies wholly in England before it enters the North Sea at Berwick.
Q 13Which river, the UK's third longest, rises in Staffordshire and flows north past Nottingham to meet the Yorkshire Ouse?
Trent
Q 21Which network of lakes and rivers in Norfolk and Suffolk was proved in the 1960s to be flooded medieval peat diggings?
The Broads
The Broads were dug for fuel by medieval monasteries, with Norwich Cathedral alone taking 320,000 tonnes of peat a year, and botanist Joyce Lambert proved the lakes were artificial.
Q 22Which lake, at 383 km² the largest in the British Isles, supplies about 40% of Northern Ireland's drinking water?
Lough Neagh
Lough Neagh was formed, legend says, when Finn McCool scooped up a chunk of earth to hurl at a Scottish rival, and a Viking fleet wintered on it in 840.
Q 23Which Welsh island was linked to the mainland in 1826 by Thomas Telford's suspension bridge across the Menai Strait?
Anglesey
The Trent has its own tidal bore, the Aegir, said to be named after the Norse sea god, which can reach 5 ft high before the river's shape at Gainsborough shrinks it to a ripple.
Q 14Which city on the Clyde, Scotland's most populous, was once the undisputed world centre of shipbuilding?
Glasgow
Glasgow is the UK's third most populous city, and NASA has named an area of Mars after it; by the late 18th century more than half of Britain's tobacco trade passed through the Clyde.
Q 15Which Scottish city, nicknamed the Granite City, became the offshore oil capital of Europe after 1969?
Aberdeen
Aberdeen's trawler fleet largely moved to Peterhead as oil support vessels took over the harbour, and the city now brands itself Europe's energy capital as North Sea reserves decline.
Q 16Which city, laid out from 1613 as Ireland's first planned city, still has its 17th-century walls completely intact?

Derry is nicknamed the Maiden City because its walls were never breached through three 17th-century sieges, the most famous lasting from 1688 to 1689.
Q 17Which national park, mostly in Derbyshire, became the United Kingdom's first when it was designated in April 1951?

Q 18Which national park, the UK's largest at 4,528 km², is an arctic-alpine plateau with long-lasting snow patches?
Cairngorms
The Cairngorms park holds more than half of Scotland's surviving Caledonian pinewood yet has only about 18,000 residents, and it was extended into Perth and Kinross in 2010.
Q 19Which Devon national park had the public's right to wild camp on its moors upheld by the Supreme Court in May 2025?
Dartmoor
Dartmoor's prison at Princetown was built for Napoleonic War captives and is reputed to be escape-proof; landowner Alexander Darwall's 2023 High Court win against campers was overturned on appeal.
Q 20Which island, where Queen Victoria died at Osborne House in 1901, hosted the largest rock festival yet seen in 1970?
Isle of Wight
The Isle of Wight's Undercliff is the largest landslip area in western Europe, and Victoria bathed there from a wooden bathing machine wheeled into the sea at Osborne Beach.
Anglesey is just 5 km² smaller than the main island of Singapore, and the Menai Strait that separates it from the mainland narrows to about 250 metres.
Q 24Which Scottish island, the third largest in the British Isles, is divided by mountains into two separately named parts?
Lewis and Harris
Lewis and Harris has no one-word name in English or Gaelic; the northern two-thirds is Lewis, the southern third Harris, and until 1975 they even lay in different counties.
Q 25Which archipelago 45 km off Land's End was nominally at war with the Netherlands for 335 years until a 1986 peace?
Isles of Scilly
The Isles of Scilly's 'war' never saw a shot fired; the islands are also the warmest place in the British Isles, averaging 12.0 °C, and St Agnes lies further south than any point on the mainland.
Q 26Which County Antrim landmark of about 40,000 interlocking basalt columns was declared a World Heritage Site in 1986?
Giant's Causeway
The Giant's Causeway's columns belong to the same ancient lava flow as Fingal's Cave on the Scottish isle of Staffa, which may be where the legend of a road built between them began.
Q 27Which Kent port faces Cap Gris-Nez across the narrowest part of the English Channel, just 21 miles, below chalk cliffs?
Dover
Dover's White Cliffs concealed a Cold War regional seat of government beneath the castle, and the strait below them is the busiest shipping lane in the world.
Q 28Which headland at 49° 57' N, with a lighthouse first lit in 1619, is the southernmost tip of mainland Great Britain?
Lizard Point
Lizard Point's first light was demolished in 1630 for lack of funds and the current twin-towered lighthouse dates from 1751; Land's End, 38 km away, is only the most westerly point of mainland England.
Q 29Which peninsula west of Swansea became the UK's first Area of Outstanding Natural Beauty in 1956?
Gower
Gower's Paviland Cave has yielded stone points made by some of the oldest modern human groups in Europe, and its Rhossili Bay coastline is a favourite of surfers.
