The Rabelo boat regatta is an annual race on the Douro River, featuring the historic rabelo boats that were once used to transport port wine from the vineyards to the caves on the river bank at Vila Nova de Gaia.
Here’s how you can save about £470 per person on a Douro River seven-day cruise - while you are actually paying full price.
The Porto connection to port wine came about during the 1700s because Porto was the port where the fortified wine was shipped from.
Amenities are few - you have to wee behind a tree and bring all the food and drink you might need, because you are often in the middle of nowhere.
Spectators near the Alfandega (customs house) could enjoy prime seating in a grandstand looking across to Gaia, while those around Ribeira and Cais de Gaia saw the magnificent views of the pilots spinning up over the Dom Luis II bridge.
