Does anyone know where I can find some good printable maps online of where the UNESCO sites are? Unfortunately my roadmaps don't list them ;-)

Also, has anyone found a Google Maps file with the 2008 sites included yet?

I would be interested too!
I have been thinking about incorporating Google Maps into the website to show the exact location of each WHS, but haven't found a really usuable source.

It isn't (as far as I know) "printable" but does go down to street level or near (depending on the country)

Select the country you want from the above page.
I would then transfer the details to the road map/guide book I was using for planning/driving. There are not that many sites in Hungary/Romania. Hope you enjoy these countries - do NOT miss NE Romania - Transylvania/Bukovina etc. Whether you bother with the Danube Delata depends on what interests you - see my review. It will take several days to really see it or else you just get a "taster" as per the villages I list in my review

I always find google earth to be the most useful as enables you to bring up all the locations of site which have multiple locations i.e. Rock art of the Iberian penisular.

The data set from the offical UNESCO site has been down for the last two weeks or so though, I guess to update with the new locations.
