Éireann (CCÉ). Fleadh 2010 was the 50th annual Fleadh Cheoil na hÉireann, and the first to be carbon neutral. That year it returned to Cavan for the first time since 1954. Up to 250,000 visitors attend the annual Fleadhann, and about 10,000 musicians compete. It is also estimated that the annual All-Ireland Fleadh generates €20-€25 million for the local economy of its host town. Heritage and tourism development In the County Heritage Plan 2006–2011, published by Cavan County Council, a guiding principle was stated as: "The unique and diverse heritage of County Cavan is conserved, sustained and, above all, cherished and celebrated by the people of the County". Located in Ireland's lakelands, the wildlife and wetlands environment of County Cavan's loughs reputedly offers opportunities for sustainable tourism development. Lough Oughter and Killykeen, located a few kilometres from Cavan town has some infrastructure for ecotourism development.
