Portugal, Comporta: Head south of Lisbon for an hour, cross the Sado River onto the isthmus called the Peninsula de Troia and you will come to Comporta, where the Sado Reserve attracts local and migrating birds and when the tide is low leaves a fascinating mudbank mozaic. Get there early enough and you could be treated to the sound of flights of Storks meeting before they go downriver for breakfast. This is a place that leaves you breathless.
