Praia de Portocelo is lovely and clean with great views and safe swimming. The water was warm and there was a great place to eat nearby. There were public toilets, showers and changing facilities, and some of the buses from Pontevedra left you at the beach, while others left you in the town of Marin, a 15 minute walk away. There was also another beach close by which you could walk to. We loved it here and didn't bother moving. The bus to Pontevedra leaves from a bus stop just off the beach opposite the bar/restaurant (which had a great meal!), and it's only a 15 minute bus ride back to the city's main station. The bus routes can be a bit confusing, so it's best to ask first. What's more, the beach is easy accessible.
