In Belgium, every month is a beer festival.
In what other country can you go into a bar and they give you a beer menu? There is a bar in Brugge that has over 1000 different bottled beers on sale! Not that I am complaining mind you.
But I did go to an organised beer festival in Djiksmuide last October ......and it was rubbish. Purely for the tourists. We stuck it an hour and went into Oostende for the night. Had a great time.
Driving from Calais to Belgium is so easy, I may pop over again in the summer.
