If you have a spare day or two and you’re happy to travel 20 miles, take a look at Serpa. This popular place has plenty of things to keep you occupied. See the sights starting with Praca da Republica, Serpa Castle and Serpa Aqueduct. Locals are also likely to point you toward Moura, 25 miles away. If you only see one thing here, make sure it’s Alqueva Dam. (But we’re also big fans of Jardim Doutor Santiago and Lagar de Varas do Fojo.)
