Adult colouring books have stormed the book charts this year and had us digging up our old colouring pencils (or pens - a contentious debate in itself).

Whether it's Millie Marotta's Animal Kingdom or Johanna Basford's Lost Ocean, these books have a way of relieving our stresses from the day and transporting our imaginations away from our to-do lists and onto otherworldly places.

There's now even colouring books for Harry Potter, Sherlock and Game of Thrones fans. And at last, there's one for those who spend their work days consumed with wanderlust - a travel colouring book.

Luxury holiday company Oliver's Travels has created the artwork based on its most stunning destinations, such as a beach house in Mykonos to a villa in Sicily.

The drawings have details such as mosaic tiles and buildings reflected into pristine pools for those looking for a challenge.

"It's not only a bit of inspiration for the kinds of beautiful places you could be staying, it's a relaxing way to while away the hours while you're kicking back on your villa holiday," says founder Oliver.

Each illustration comes with an image guide so you know exactly what you're colouring in (aka which shade of blue to use).

And the best part? It's absolutely free. Take a preview of the book below and download a copy to print off at oliverstravels.com.
