Amazing Galicia
Guarda is a very nice town and also a good base to visit the surrounding areas, the Jewish quarter is very interesting as well as the impressive Cathedral
either walk a lot or use the public transportation that is very good, for example take the tram from the city center up to the Castle and Cathedral and then walk down to town, long walk but worthwhile
Its a must visit site and the archeological site is amazing as well, well worth to climb up to see the theatre
