Travel to Tuy by bus or train...
Travel to Tuy by bus or train - only the two trains a day which go on to Portugal stop here but Guillerey station is more used nad very near.
Fortified cathedral and area around it are scenic and interesting. Bridge into Portugal worth seeing- Eiffel. Good to return to Vigo by bus to A Guardia and then bus via Baiona.
