Before leaving Latvia, it is advisable to exchange Latvian lats back to your foreign currency, unless you want to keep them as a souvenir. This isn't such a bad idea, since the Latvian Lat is one of world's most beautifully designed currencies, especially the many different types of 1 Lat coins and also the paper notes. Keeping Lats would also be a good reason to visit Latvia again. However, hurry up, since the Euro will be introduced in a couple of years.
