Flooded gravel pits became an island thrill capital: Hyperia climbs 71.9m and tops 80mph at Thorpe Park in Chertsey, the UK's tallest and fastest coaster park.
Exactly 95 days after he cut the ribbon at Thorpe Park in Chertsey, United Kingdom, Lord Louis Mountbatten was dead, assassinated by an IRA bomb off the Irish coast. The park he opened on 24 May 1979 was a gentle water-and-heritage showcase built inside flooded gravel pits. Today the park is the UK's tallest, fastest scream factory — and the water still remembers the gravel.
Thorpe Park sits off Staines Road, about 20 miles southwest of central London, on a site quarried for gravel from 1941 into the 1970s. Ready Mixed Concrete dug out millions of tonnes of aggregate to rebuild London and lay the M25. When the pits flooded, RMC turned them into an island-like water park with mock Viking longships and model aircraft.
The pivot came in 1998, when The Tussauds Group bought the park and aimed it squarely at teenagers. Hyperia, opened in May 2024, stands 236 feet (71.9 m) tall — roughly the height of a 23-floor office block — and tops 80 mph. Yet goldeneye and gadwall ducks still winter in the quarry lakes directly beneath the coaster tracks.

History
Long before the first roller coaster, this corner of Surrey was a Thames gravel terrace. Mesolithic hunters, Iron Age farmers, and Roman settlers left traces in the river gravels. A charter from 672–674 records that Frithuwald, sub-king of Surrey, and Abbot Erkenwald granted five hides at Thorpe to Chertsey Abbey. The Domesday Book later lists the manor as Torp.
That same gravel became the site's second life. Between 1941 and the 1970s, Ready Mixed Concrete scraped out millions of tonnes of aggregate for post-war London and the M25. When the pits flooded, the water stayed. Every coaster queue now winds along peninsulas built for conveyor belts and quarry haul roads.
The turning point
On 24 May 1979, Admiral of the Fleet Louis Mountbatten, 1st Earl Mountbatten of Burma, arrived to open Thorpe Park. He was 78, a former Chief of the Defence Staff and last Viceroy of India, and he lent his name to a park that was then about water and maritime heritage, not adrenaline — a late-career endorsement for a statesman making fewer public appearances. Ready Mixed Concrete wanted a statesman to bless its flooded gravel pits as a national showcase.
The turning point came 95 days later. On 27 August 1979, an IRA bomb exploded aboard Mountbatten's wooden fishing boat 'Shadow V' off Mullaghmore, County Sligo, killing him. That made the Thorpe Park ribbon-cutting one of his final major public appearances. The park he opened as an eco-leisure experiment would not stay gentle for long.
In 1998, The Tussauds Group bought the site and began converting it into the UK's thrill capital. The water remained, but the mission changed. Mountbatten's maritime heritage park is now better known for Hyperia's 236-foot drop than for model longships.
Yes, if you want the UK's tallest and fastest coaster and a set of islands built in flooded gravel pits. Hyperia lifts you 236 feet—over 70 metres—then drops past the lake at more than 80 mph. Skip it if you're after a gentle family day; Chessington or Legoland fit that better.
A full day, 7 to 9 hours, covers the main coasters without feeling rushed. Off-peak weekdays or Fastrack passes can squeeze the headliners into 4–6 hours. For Fright Nights or summer peak, stay from the 10am gate to close.
Take South Western Railway from London Waterloo to Staines, then the 950 Thorpe Park Express shuttle bus. The train takes 30–50 minutes; the bus leaves from outside Staines station from 9:05am and drops you at the park entrance. Driving means M25 junction 11 or 13 and the A320, but summer traffic stacks up.
Early June weekdays or late September outside school holidays give lighter crowds and decent weather. October Fright Nights is the most atmospheric, with coasters running in darkness until 9pm, but queues swell. Avoid August weekends if you don't enjoy 70-minute waits.
No, standard entry is not free, but children under 1.2 metres enter free with a paying adult. Advance online tickets run £29.75–£34.13, much cheaper than the £68+ gate price. The Island Return Guarantee also gives a free return visit if rain closes rides for over an hour.
Ride Hyperia first, the UK's tallest coaster at 236 feet. Then hit Stealth for a 0–80 mph launch in 1.8 seconds, and The Swarm's near-miss keyhole through a ruined church set. The Tidal Wave splash bridge gives the best photo wall of water.
Hyperia, a steel hypercoaster standing 236 feet (71.9 metres), is the tallest and fastest ride in the UK. It opened in May 2024 and reaches over 80 mph, with a non-inverting loop over the lake. Its station sits in Fearless Valley with gold and white track.
Not really; most major coasters require 1.4m height and the park is aimed at teens and adults. Small children get free entry under 1.2m, but they'll find only a handful of gentler rides and beach areas. Choose Chessington or Legoland for under-10s.
