The tallest trees in the world are a type of conifer called coastal redwoods, often exceeding more than 100m in height.
Their girth is pretty huge too with trunk diameter of around 9 metres (30ft) on average
Equally impressive is their longevity, with many trees reaching their 1,000th birthday. The oldest known redwood is thought to be an eye-popping 2,200 years old.
At almost 116 metres high the tallest redwood in the world – and therefore the tallest tree in the world – is a 600-year-old (roughly) tree known as Hyperion, situated in Redwood National and State Parks, Humboldt County (a UNESCO World Heritage site).
This is almost double the height of the UK's tallest tree, the Stronardron Douglas fir in Argyll, Scotland
Coastal redwoods are found along the USA's Pacific coast, from southern Oregon to central California.
