Feria de la Gamba
Seafood celebration on the Huelva coast

Normally taking place over a weekend at the end of April, this festival celebrates the prawns, baby clams and fried anchovies for which the Huelva coast is famed.
Very popular, so be prepared to wait a little to get served, but the atmosphere is fun and friendly.
If you are not seafood fan you can always settle for sampling the local cheese and ham.
