Paseos rurales. Istán (en inglés)
Istán is like a spot of bleached white plaster in the middle of the green mountainside. The predominant sound that can be heard in its streets is that of water which seeps out of the stones, flowing al ng the irrigation ditches and channels into the terraced plots of land. All this water, of course, fruit of Rio Verde (Green River) is born and dies in the municipality as it runs into the reservoir that supplies the whole of the Costa del Sol with water all year round.
Visitors can notice when they are getting near I tan, which is located within the Biosphere Reserve, the quality of the light changes. This is due to the subtle combination of colours that are created as the pine, oak and Holm oak trees mix with the bluish reflection from the Green River's reservoir.
It is within this beautiful landscape that one of the most famous examples of the Holy Chestnut Tree can be seen. This enormous, ancient tree is probably the oldest within the whole Sierra de las Nieves park and is dated back between eight hundred and a thousand years. It is about thirteen metres round at the bottom and has been declared a Natural Monument by the regional government (Junta de Andalusia).
