I can highly recommend the River Ebro in Spain.
for some of the best fishing in Europe
Big Catfish, Carp, Zander etc.
Cheap flights with easy jet or Ryanair into Reus
or Barcelona.
Lots of cheap B&B around Tortosa or rent a
caravan by the river.
Good local restaurants and cheap booze
I had my first catfish there, an 87lb Zoo creature.
They go up to 200lb.
Google 'Catfish Ebro' for lots of Brits offering
boat fishing and 'all included' trips.
Planning a trip myself soon... cant wait.
