The Siberian-born stuntman – known to as Oleg Cricket to his thousands of Instagram fans – is renowned for his vertigo-inducing gymnastics at the summit of the earth’s highest peaks.

For his latest video, Oleg was flown to Russia and Hong Kong by hotel booking website Travel Ticker, for a spot of extreme sigtseeing.

Standing on a blue laddered balcony in Russia, he leaps casually from rung to rung, seemingly oblivious to the stomach-turning drop below.

He then performs roly-polies and a backflip on a ledge only marginally wider than he is.

In Hong Kong, Oleg wears a bodycam and strolls along a wall, jumping between balconies as if he was hopping over a puddle.

It’s all in a day’s work for the parkour expert, who shot to fame by posting Instagram images of himself dangling hundreds of feet above the ground while grasping a friend’s arm.

Since then he’s continued to seek even greater, more terrifying thrills.

Only recently he was seen whizzing around the edge of a Dubai skyscraper on a hoverboard – while doing a hand stand.
