Reaching a sagra
Indeed, most of the sagras are organized in small villages or hamlets. A sagra is often the most important festive period of a community, so the place where it takes place must contain a lot of people: it can be a football field, a meadow or a big square. In cold seasons a hall, a ballroom or something like this.
It's absolutely a good idea to arrive early. Dining often starts at 7 or 7:30 pm, so it would be better to be there not after 7:30 pm and, if possible, even earlier. The "rush time" in a sagra, generally from 8 to 9.30 p.m., can be incredibly crowded, and sometimes we've waited for our food for literally hours!
As a sagra is usually an important event, so some signs, like banners or posters will help you reaching the place.
