International travel media company Lonely Planet has launched a free digital guide to the world's greatest LGBTI Pride celebrations.

Lonely Planet's Guide to Pride: 20 Cities & Their Celebrations features not only the when and where of Pride celebrations world-wide, but also has a list of the best gay-friendly places to eat, drink and stay.

When loaded onto a mobile device, the guide allows users simply to tap their screens to access each listing's website or phone number.

"Lonely Planet's Guide to Pride is a resource - and hopefully a source of inspiration - for LGBT travelers, who have long been part of the Lonely Planet community," Lonely Planet's Chris Zeiher said.

"Even if you miss Pride, the destinations and travel tips in this book will serve you year-round."

Over the last 40 years Lonely Planet has grown to be a trustworthy source of information for all kinds of travellers and has printed 130 million books in 13 different languages.

Their Guide to Pride covers Amsterdam, Atlanta, Auckland, Berlin, Buenos Aires, Cape Town, Dublin, London, Madrid, Melbourne, New York City, Paris, Puerto Vallarta, Rekjavík, San Francisco, São Paulo, Sydney, Taipei, Toronto and Vancouver.

The Guide is only available through the iTunes store: itunes.com/prideguide.
