Mrs. Anywhere and I spent about 4 days there about 10 years ago, after spending 10 days in Paris and the south of France. We really enjoyed the laid back atmosphere of Brugge. In fact we extended our stay by a day rather than going to Brussels a day early for the flight home.

In addition to the main tourist attractions mentioned by bamboola and Djlawman above (although we toured a different brewery), we also rented bikes for 2 half days - rode along a canal to the Northest to a small town for lunch (don't remember exactly where) one day, and through the countryside to the Southwest another day.

If you happen to be there on Market Day - Wednesday or Saturday - that's worth checking out too.
