What is the best rollercoaster in UK?

The best rollercoaster in the UK, as voted for by the public in 2021, is Stealth at Thorpe Park.

Stealth is a launch roller coaster, which means it uses a powerful linear induction motor to accelerate riders from 0 to 80 mph (128 km/h) in just 2.5 seconds. The coaster then takes riders up a 200-foot (61 m) hill before dropping them back down to the ground. The entire ride lasts for about 30 seconds.

Stealth is one of the most popular roller coasters in the UK, and it is often ranked among the best roller coasters in the world. It is a thrilling and intense ride, and it is not for the faint of heart.
