The sweet chestnut trees that surround us – hence Hotel Los Castaños (the tree is masculine in Spanish, the fruit is quite rightly feminine) have performed their annual magic trick. Suddenly the green Alto Genal valley is red and orange and gold and yellow and all the colours in between. When the sun shines directly on the leaves, it is breathtaking. My photograph taken this afternoon hardly does it justice – you need to see it to believe it! Don’t you just love deciduous trees – such versatile creatures.
