Bulgaria offers a diverse range of countryside from majestic snow capped mountains, to flat plains, rolling fields and then the sandy beaches along the southern part of the coast and the more craggy areas to the north. There are numerous lakes and dams, gorges, caves and rock formations. There are many monasteries, ruined fortresses, archaeological discoveries such as the Thracian King Tombs around Kazanlak and the old fortress and temple carved out of stone at Perperikon down towards Kardjhali.
