Since the rerouting of the Lusitania comboio Hotel Lisbon to Madrid service, there have been questions about how to get from Marvão in the Alentejo to Caceres in Spain.
I have made contact with the tourist posts in each centre and can confirm as follows:
1) There is currently no bus/train link between Marvão and Spain.
2) From Marvão one can get a taxi to Valencia de Alcántara, 24km away in Spain.
2) From Valencia de Alcántara there are buses to Caceres as follows:
Monday to Friday - Dept: 7:30H, 10:00h and 15:30
Sat. 7:30H
Sun. 17:15h
Details correct at time of writing.
