In reply to Sam Mayfield:
A Coruña - nice coastal town
Costa do Morte - beautiful secluded white sand beaches. Rugged coastine.
Santiago de Compostela is definitely worht a visit - full of tourists but a lovely centre. Wander round the streets at night
Rias Baixas - a series of 3 river inlets on the west cost just above the portuguese border. Nearest towns are Pontevedra and Vigo. Home of Albariño white wine. Quite touristy but in a good way. Here are a few things you can do there:
- A boat trip to sea the mussel colonies was surprisingly good fun. We had dolphins jumping along the side of the boat the the organisers serve huge buckets of mussels and cheap white wine. Go to the harbour in O Grove and there are plenty of place to get the boat.
- Have lunch at the Costa da Vela in Cabo Hom (both on Google Maps). It's a nice rustic place, a bit out of the way, good seafood and nice wine.
- Hang out in Pontevedra - it has a beautiful town centre - well worth the vist
- Visit wineries. The area from the AP-9 to Cambados is the centre of Albariño production.
- Islas Cies - uninhabited islands about a 20-minute boatride from Vigo. To be honest they are a bit over-rated because they can get very touristy. I preferred the beaches on the mainland.
