Maps
In Poland i used
the "Polska mapa campingów, 1:750 000, 2000, PPWK,
ISBN 83-7000-729-6". There's just enough information on the map to use
for cycling but a more detailed map is recommended.
For the Baltic States i used "Baltic State Road Atlas, 1:500 000, 2000/2001,
Jana seta Kaunas, ISBN 9984-07-187-1".
It's an easy readable map and very accurate. The atlas also contains 71 citymaps.
This map is definitely recommended for cycling.
