In reply to AdamBrown:
At Comares there are three separate Ferrata on the same cliff all good fun and at least one ok for a complete beginner, all 2 minutes from the car park.
There is a lovely ferrata at Gaucin, the Castillo del Alguila. After a traverse this has a bridge and a zip wire linking two separate pinnacles from the main cliff which is the castle cliff and has great views. The zip is a bit quick on a pulley but should be ok on crabs
The ferrata at Rhonda was very disappointing.
There is a ferrata at El Chorro near to the town but I haven’t done it. It is near to the end of the Camino del Rey which itself is worth doing although now it is very commercial.
There is also a three section ferrata at El Torcal national park.
