We love Corcubion and have anchored there twice now, the last time for 5 days. It is on the ‘reverse Camino’ from Santiago to Finisterre, which pilgrims walk to see the ‘end of the earth’.
There are a good butcher and small grocery store, but neighbouring Cee – a short bike ride or 20-min walk away – has a giant supermarket inside a mall, good hardware store, and a fresh produce/fish/meat market. The sailing club restaurant is quite good and popular.
