Wikipedia founder Jimmy Wales is proud to launch the WikiVoyage on January 15. Wikivoyage will have more than 25,000 articles on places around the world. The site features articles viewable on desktop, tablet and smartphone. And also available for download in PDF format.
Here is a description on the WikiVoyage site: Wikivoyage is a project to create a free, complete, up-to-date, and reliable world-wide travel guide. Whenever travellers meet each other on the road, they swap info about the places they came from and ask questions about places they’re going. We want to make it easy to share that knowledge and let others share it.
