The nearby town of Vila Real de Santo Antonio took over Castro Marim's importance when it was completely rebuilt by the Marques de Pombal after the earthquake of 1755. With the construction of the bridge in 1991 across the River Guadiana it now provides a speedy driving connection with Seville and the rest of Spain. To the south of the town is the popular beach resort Monte Gordo that offers the tourist kilometres of sea washed sandy beach and bathing.
There are three golf courses in the area. The outstanding 18-hole Monte Rei Golf Course, the 27-hole Castro Marim Golf Course and the 18-hole Quinta do Vale Golf Course.
