In reply to Rich Mayfield:
Regarding the cliffs at Moraira, there's info online from the local authority to ask for no further development. The bolts / fixed gear that remains is in such a poor state that most would turn away and go somewhere else anyway. As I understand it there is no issue to climb any of those routes using traditional protection. This cliff also seems to attract many snakes to its base and rock, in case anyone needed further persuasion to look elsewhere!
Morro Falqui: As Rich mentions, there's apparently a signed letter from the Mayor. Further to this, quite recently a prominent information board was erected at the lower entrance to Sonjannika (at the head of the barranco), this showed how to access the beach via fixed ropes installed by the local authority. There is no indication on this board to suggest climbing is forbidden. My experience of these info boards here is that they will make any access issues very clear (Relleu VF / Orihuela Pared Negra / Ponoch VF / as examples).
When the fixed ropes in the canyon were being replaced by local authority workers, we accessed the cliff and briefly chatted to the guys working there. We told them we were going climbing on Sonjannika and there was no suggestion from them that wasn't completely fine.
