About this guide

Douro by the Glass is an independent guide to wine tours in the Douro Valley, Portugal, and to the day trips that reach it from Porto. We are not a winery, a tour operator, a tourism board or GetYourGuide, and the site name describes what we write about rather than a business. For official tourist information, see visitportugal.com.

Facts here are checked against the operators' own listings on GetYourGuide and against official sources such as UNESCO, the port wine institute IVDP, the rail operator CP and the weather service IPMA. Itineraries, opening hours and seasons change; when a listing and this page disagree, the listing at checkout wins.

The site is funded by affiliate commissions: when you book through a GetYourGuide link here, we may earn a commission at no extra cost to you. That never changes what we recommend, including telling you how long a day trip spends on the road. Details on the affiliate disclosure page.
