Luxury dog-friendly hotels in Douro Valley, Portugal

A striking, sun-kissed mountainscape, neatly combed with vine-filled terraces, where the tranquil River Douro lazily winds its way from the Atlantic coast to Spain. On its gentle journey, it passes through the oldest wine-producing region in the world: little wonder these wild, earthy winelands have been awarded Unesco World Heritage status. Portugal’s second largest city, Porto stands proudly on Douro Valley’s oceanside edge; from here, you can follow the river into the fertile region once best known for Mateus rosé, but now celebrated as an epicurean paradise.
