If you are in Andalucia and near Malaga I recommend the "Jardin Botanico de Cactus y otras Succulentas" of Casarabonela. It is now run by the local council and has a lovely collection of aloes, agaves and other succulents, sone outside and others in a greenhouse. The photo was taken late this Spring. Website is
