Guidebook publisher Lonely Planet hops aboard the adult colouring bandwagon this month with its Ultimate Travelist Colouring Book, featuring “the world’s 100 greatest places, as voted by travel experts at Lonely Planet”.

Said to promote “mindfulness” and relieve stress, grown-up colouring books are also pushing the nostalgia button with travellers for whom simpler editions were long ago provided by parents on long car journeys. They perhaps remind us, too, of a less-mindful time when colouring was just “something to do” to ward off the monotonous back-seat mantra, “Are we there yet?”.

Among Lonely Planet’s 100 drawings for colouring in are the Eiffel Tower; Piazza San Marco, in Venice; the Sagrada Familia, in Barcelona; the Sydney Opera House; and Moscow’s Red Square. Places in China include The Great Wall, Tiger Leaping Gorge and the Forbidden City, but Hong Kong has been left out. A few sample pages and a full thumbnail list of contents can be found at shop.lonelyplanet.com

Among the more popular travel-related colouring books published last year was the Color Your Way To Calm series(Splendid Cities, Secret Paris, Secret New York and Secret Tokyo), which can all be found at Amazon.com.
