Saga is set to launch a second river cruise specifically for solo travellers after the first sold out.
The Douro Discovery cruise on November 3, 2016, offers single travellers the opportunity to sail through Portugal and Spain.
Guests fly to Porto to meet their river cruise ship, the 40-cabin Douro Princess at Vila Nova de Gaia on the south bank.
After an overnight mooring, guests start the cruise with lunch at the 14th-century former Monastery of Alpendurada, before sailing to Régua.
Next on the itinerary is a visit to the ancient city of Lamego to view the elaborate Sanctuary of Nossa Senhora dos Remédios, which overlooks the town.
Douro Princess cruises on to Pinhão for a winetasting at nearby Quinta do Seixo and an excursion to Figueira Castelo de Rodrigo, a medieval village set atop a hill beside the River Côa. For more details, click here.
In April, Saga’s announced its first river cruise for solo travellers, which sets sail on October 14, 2016 for seven nights.
The Autumn Colours of the Rhine cruise starts in Bonn, Germany, with coach travel from Folkestone via Eurotunnel.
