Follow the N-332 a little farther to Vera, then take the road to Garrucha and the coast (the N-340 continues inland until Almeraa).
If you follow the N-332 a little longer, it will lead you to a road you can take to Garrucha and the coast.
If you go a little farther on N-332 towards Vera, you won't be able to get to the road to Garrucha.
