Apple CEO Tim Cook is having a wonderful European adventure

Apple CEO Tim Cook is in Europe and he's having a wonderful time. 

We know this because Cook has been publicly sharing updates about his travels with his 4.1 million Twitter followers, posting a stream of new photos with the zeal of a work colleague flooding their friends' timelines with vacation photos.

While it looks like Cook is having a blast in his posted photos, it's a business trip. A French startup CEO told Business Insider that Apple people contacted him 10 days ago to help set up one of Cook's meetings, so that he could learn more about French app developers. Cook is also set to give a speech at the University of Glasgow in Scotland on Wednesday.

Even so, Cook appears to be eating well, meeting interesting people, and getting spotted everywhere he goes.  And he's dutifully chronicling it all on Twitter - of Cook's 328 total tweets, 8 of them are from this trip. 

So far this week, he's visited France and Germany, and the trip's not over yet. 

Here's a quick look at his European travels:
