WATCH: Tsitsipas leaves Iceland for Oman

Stefanos Tsitsipas has been making the most of his offseason Iceland and Oman vacation, at least in terms of building up his YouTube portfolio.

The ATP Finals champion had already made two videos on his trip, called "THE ICELANDIC TEMPTATION" and "Training with the WORLD'S STRONGEST MAN!" Now, he's come out with a third, titled "IT WAS F*CKING COLD!"

In the vlog, Tsitsipas visits the site of the Solheimasandur plane crash and the surrounding black-sand beach.

For the finale, Tsitsipas is challenged to get into an ice-cold river.

"Oh my goodness this is so cold! I'M INSANE!! I'm CRAAAZZY!!! WhOOhOOhOO!" he exclaims. "SO F*CKING COOOOLD! AhhHAHAA! MAN! AhH AgH Ohh. This is too cold for me, man! You have no idea how cold this is."

But Tsitsipas is not done yet. He left the cold for the Middle East, finding a new vacation destination in Muscat's 70-plus degree weather.

Iceland has proven to be a popular place among ATP and WTA players this offseason, getting visits from Dominic Thiem ...

And Elise Mertens:

When you chase the sun around the globe for most of the year, maybe the cold climate is refreshing. Getting in the river, though: not so much.
