Climbing Britain's tallest tree
A tree in Scotland has officially been named as the tallest in Britain.
The 135-year-old grand fir lives on the banks of Loch Fyne in Argyllshire, and it's a massive 64.24m tall!
It took a team of expert climbers hours to get to the top. They then hung a piece of rope to the ground and measured it when they were safely down.
It's thought the tree has grown so high because there's lots of rain in the area, and during the summer it gets a lot of sunlight.
Don't try to climb trees this high as it's really dangerous!
