Josefuv Dul Hike, Picture 3, near Bedrichov, Liberecky Kraj, Bohemia(CZ), 2007

In this picture, shot a little bit further down the trail, you can see Jablonec (or at least that's what my Czech travelling companions said), and further away, Liberec. That antenna up on the mountain isn't actually an antenna at all, but the famous Hotel Jested, perhaps the most unique hotel design ever. Here's their website if you want a closer look, as this was the closest I got:

I do have the goal of getting there to take a closer photo sometime, but on my most recent, and so far only, Liberec trip I never got to it.
