Despite the country's economic troubles, tourism in Bulgaria has risen rapidly since the end of Communist rule. The tourist industry is in the process of becoming totally privatized, a development that is expected to improve the quality of the tourism infrastructure. Bulgaria is rich in mineral waters and has numerous tourist spas. Visitors are attracted to the Black Sea resorts and the Balkan mountains. Foreign visitors to Bulgaria must have a passport and, depending on their nationality, may require a visa.
In 2000, tourist receipts totaled approximately US $1 billion as the number of foreign visitors totaled 4,922,118. That year there were 120,150 beds available in hotels and other establishments, with an occupancy rate of 28%.
In 2002 the US government estimated the cost of staying in Sofia at $215 per day. In smaller towns the daily costs were approximately $90.
