The Cool Earth foundation works to conserve rainforests across the world in an attempt to decrease Carbon emissions, whilst also supporting local communities. The Fair Earth Foundation CIO, a registered UK charity, runs in the first week of every month a special challenge to climb Mt Teide, the third highest volcano in the world. This is a gruelling, arduous challenge but the view at night of the stars and the breaking dawn over the magnificent crater make it consistently the single best experience of our volunteers in Tenerife over the last thirty years- thousands have taken up the challenge!!
