We have seen a lot of campers and motorhome s in the free car parking on the feria ground in fuengirola, and on the free car park in la cala de Mijas. There is a camping site just outside fuengirola near el faro but it looks cramped and a bit tatty from the outside. Never camped there though.
There is a nice looking camping on the lake just near la vinuela and there is a great restaurant too
Hope some of that may be useful :hello
