Lisbon? Tick. Porto? Tick. The Algarve? Tick. That’s Portugal done, then? Well, no, not really. There are huge swathes of the country that often get overlooked, such as the Côa Valley near the border with Spain, which has two prehistoric rock art sites. There’s Chaves, a charming town also in the north famed for its healing thermal waters. There’s the Ria Formosa national park with its lagoons, flamingos, salt pans and tidal islets, which stretches down 35 miles of the coast. We’d like to hear about your Portuguese discoveries off the beaten track. It could be anything from a little taverna in a hilltop village, a river beach in a national park, or a farmstay in the Douro Valley

If you have a relevant photo, do send it in – but it’s your words that will be judged for the competition.
