Host: Camara Municipal do Porto
Tip: The riverside Ribeira and the Fontainhas neighbourhood are the liveliest; base in Porto for the night, then escape to the quiet valley to recover the next day.

Across the vindima, quintas open the harvest to guests for grape picking on the terraces, traditional foot-treading in granite lagares after dark and long harvest feasts. It is the most atmospheric time of the Douro year.
Host: Douro quintas and tour operators

Host: Municipality of Peso da Regua
Tip: It coincides with the start of the harvest, so pair it with a quinta visit nearby to watch picking and fermentation begin.
