Baiona has a lot of charm with a quaint fishing port, a number of small but appealing beaches, plus an old town that sits just behind the main seafront area. There are also many small beaches along the coastline within close proximity to Baiona and this is one of the reasons why it is so popular with summer visitors.
There are quite a few churches and other small buildings of architectural and historical interest, but Baiona's most prominent building is the Castelo de Monterreal, a castle that sits to one edge of the town. You can visit Castelo de Monterreal and it affords excellent views of Baiona and the surrounding coastline from its elevated position.
Within Baiona's old district there are a number of narrow corridor like streets with typical Galician terraced houses lining them. This area is pleasant to walk around and it gets you away from the busier seafront zone which is more commercialised. There are bars, cafés and restaurants hidden away in this area and most are superior to, and often cheaper than, the ones found on the ocean front drive.
