 Tourism is nowadays the main source of income in Clwyd . The upland areas with their sheep farms and small , stone @-@ walled fields are attractive to visitors , and redundant farm buildings are often converted to self @-@ catering accommodation while the farmhouses themselves supply bed @-@ and @-@ breakfast opportunities . The arrival of the railway on the coast in the mid @-@ nineteenth century opened up travel from Merseyside and caused a boom in tourism , with guesthouses in seaside towns offering board and lodging for the urban visitors . More recently caravan sites and holiday villages have blossomed and there has been an increase in the ownership of " second homes " .
