Discover the delights of northern Spain and northern Portugal with this fabulous two-week tour. Starting and finishing in Santander, the tour will head south to the enchanting city of Salamanca, before crossing into Portugal. Drive along lanes lined with olive groves, along the border towns, guarded by centuries-old castles. Discover the enthralling Serra da Estrela mountains, before turning north to the Douro Valley, where you can learn all about port wine production. Spend time in the wonderfully Dickensian city of Porto before spending a couple of days wending your way gently through the very north of Portugal and back into Spain. The final night of the tour will be in the awe-inspiring Picos de Europa mountains.
