3 Glaswegians took the 1600 tour from Pinhao for 31.25 euro on 30 July. Loved the stillness of the Douro on a hot 33C day , the scenic and panoramic valley views, and chilled soft drinks at reasonable prices from a friendly crew.
My personal highlight was sufficient time ( 50-minute cruise) to witness my frazzled and grumpy 8YO son return to his energetic and gregarious best in time for the long return trip back to Porto. Special thanks to Ian (Spurs fan from London) and his party for not throwing Conor (and his Arsenal kit) overboard - it was a pleasure being in your company!
Finally, as a user of Calmac ferries and various other services abroad, I really do not understand some of the negative feedback posted. The trip duration was just right for us, filled a gap and was very relaxing indeed. I would recommend this company to Trip Advisor users, If you really want a longer cruise, try a one-way trip from Regua to PInhao (or vice versa) .
