Explore Estremadura and Ribatejo
The Grutas de Mira de Aire are Portugal’s largest show caves, set just outside the drab textile town from which they take their name. The caves comprise a fantasy land of spaghetti-like stalactites and stalagmites and bizarre rock formations with names such as “Hell’s Door”, “Jelly Fish” and “Church Organ”. The 45-minute guided tour (in English on occasion) culminates in an extravagant fountain display in a natural lake 110m underground; you then take the lift up to emerge beside an aquatic park (summer only), a great place to cool off.
