The Loire Valley offers many opportunities for the angling enthusiast with both fast and slow flowing waters. The Loire river, which is the longest river in France, can be fished for bleak, gudgeon, roach, chub and pike. In summer, parts of the Loire have mullet swimming up river from the sea. One of the tributaries of the Loire, the River Cher has pike, perch, trout and carp. There are numerous lakes for carp fishing which is very popular in France and in the canals you can find eels and crayfish. Permits are always required. These can be obtained from tabacs, tackle shops and Post Offices.
