This is a very cool postcard because the top is actually a book mark you can tear off and I really love the stamp and the dog sticker that got the postmark :P
Gorski Kotar (English: Mountain District) is the mountainous region in Croatia between Karlovac and Rijeka. Together with Likaand the Ogulin-Plaški valley it forms Mountainous Croatia. Because 63% of its surface is forested it is popularly called: "The green lungs of Croatia" or "Croatian Switzerland". Through the region passes the European route E65, which connects Budapest and Zagreb with the Adriatic Port of Rijeka.
