On my fist trip around Eastern Europe a few years back I picked up a copy of Krakow In Your Pocket, and was impressed. In Vilnius I found another. The same happened in Tallinn. An isolated incident became a chain of events. Consistently the guides were well informed, saturated with local insider info...and most interestingly...bloody well written. I implore you to head over and have a proper browse of their site- everything is syndicated online, and now allows you to leave comments. If print is your thing, you can order copies from the site, or download many of the guides in PDF.
Probably the most exciting thing about IYP is their determination to cover the lesser trodden paths of Eastern Europe...including places whose causes deserve a bit of trumpeting, especially in the Balkans. Their guides to Kosovo, for example, are fascinating.
Whilst we're on the subject, do have a look at their blog, which covers the quirks of that rather newer side of the continent (a bit like English Russia, but with broader scope). And if you happen to be in Belfast this thursday do pop along to the open top tour of the city to celebrate the launch of the second edition of the In Your Pocket guide to the Northern Irish capital- the only country in Western Europe that IYP cover (other than the Germany, but that's a gray area) The lovely Heidi McAlpin, who helped me out on this piece, will be your host- contact email@example.com for details.
