Deborah,
We also struggled initially getting suitable maps for the Alpujarra region of Andalucia. We eventually found a good source at Stanfords of Longacre, London (0207 836 1321, www.stanfords.co.uk ). It may be worth a try
Maps of inland Spain are hard to come by and are generally very poor at indicating rights of way and footpaths. Mapa Guia Parque Natural Sierra Subbeticas, 1:50,000 by Junta de Andalucia, covers most of the area you are interseted in, on a single map.
The series Cartografia Militar de Espana 1:50,000 is drafted a little more clearly although the paper is of poor quality. Four maps of this series, Lucena(17-40), Baena(17-39), Alcala la Real(18-40) and Alcaudete(18-39) together cover your area of interest.
All of these should be available from Stanfords where they retail at about £6 each and can be ordered over the telephone.
To get hold of them much more cheaply visit the map shop at: Libreria INE, Calle Panaderos 2, Malaga
