The latest patch introduced the Labyrinthine Cliffs. This is a region in Maguuma Jungle that is only accessible by boat (you take it in Lion’s Arch). Labyrinthine Cliffs is high up in the air, so there is a lot of jumping. I found it so beautiful that I decided to add it to the screenshot gallery.
Sadly, it’s temporary content and will go away in less than a month again. Try to have a look at it yourself or just leaf through the pictures here. ;) I don’t remember right now, but it may reappear in the future as ArenaNet said that they will have some content be recurring.
Note: It took me quite some time to take all those screenshots, sort through them and upload them here. However, they’re not just for looking. If you want to use them (e.g., as a desktop wallpaper, for fanart, in your blog,…) feel free to do so – as long as it complies with ArenaNet’s copyright, of course, and you’re not saying it was you who took those screenshots. ;)
