Rwanda’s service sector suffered during the late-2000s recession as banks reduced lending and foreign aid projects and investment were reduced. The sector rebounded in 2010, becoming the country’s largest sector by economic output and contributing 43.6% of the country’s GDP. Key tertiary contributors include banking and finance, wholesale and retail trade, hotels and restaurants, transport, storage, communication, insurance, real estate, business services and public administration including education and health. Tourism is one of the fastest-growing economic resources and became the country’s leading foreign exchange earner in 2011. In spite of the genocide’s legacy, the country is increasingly perceived internationally as a safe destination; The Directorate of Immigration and Emigration recorded 405,801 people visiting the country between January and June 2011; 16% of these arrived from outside Africa. Revenue from tourism was US$115.6 million between January and June 2011; holidaymakers contributed 43% of this revenue, despite being only 9% of the numbers. Rwanda is one of only two countries in which mountain gorillas can be visited safely; gorilla tracking, in the Volcanoes National Park, attracts thousands of visitors per year, who are prepared to pay high prices for permits. Other attractions include Nyungwe Forest, home to chimpanzees, Ruwenzori colobus and other primates, the resorts of Lake Kivu, and Akagera, a small savanna reserve in the east of the country.
