Sierra Nevada National and Natural Park

Listen for a moment. Somewhere close by, water is running. It is not a river. It is a narrow channel of cold water, cut into the hillside, moving fast between stones and grass. Above you, the slopes climb toward a high, bare ridge. Below you, terraces step down the valley like a long staircase. This is the southern face of the Sierra Nevada, and this mountain range shapes almost everything you can see.

The Sierra Nevada stands in Andalusia, in the south of Spain. It runs across the provinces of Granada and Almería. Its name means the snowy mountain range, and for much of the year the high summits carry snow. The highest peak, Mulhacén, rises almost three and a half thousand metres. It is the highest point on the Spanish mainland. On a clear day, people on the summit say they can look south across the Mediterranean toward the mountains of North Africa.

The protected area has more than one layer. UNESCO named the range a Biosphere Reserve in 1986. A natural park followed in 1989. Then, in 1999, the highest and most fragile zone became a national park. So the name you see on the signs, National and Natural Park, is not a repetition. It describes two levels of protection. The national park covers the high mountain core. The natural park forms a wider ring around it, where villages, farms, and grazing land continue.

You are standing in the Alpujarra, the long valley system on the southern slopes. The municipality around you is called Alpujarra de la Sierra. It brings together several small villages, including Mecina Bombarón and Yegen. Here, the mountains are not a wilderness set apart from people. They are a working landscape. Look at the stone walls, the chestnut and walnut trees, the small fields of vegetables. Each one depends on water that comes down from the peaks.

That water brings us to the first surprise. The irrigation channels here, called acequias, are very old. Many date back to the medieval period, when this region was part of al-Andalus, the Muslim world of the Iberian Peninsula. Farmers built channels to catch snowmelt and guide it slowly across the hillsides. Some channels even let water sink into the ground on purpose, to feed springs lower down. Today, local communities still maintain many of them. The sound you heard at the start may be one of these channels.

The villages carry the same heritage. Notice the flat roofs, often covered with a grey clay soil. Notice the tall, round chimneys with small stone caps on top. The houses cling close together on the slope, with narrow lanes between them. This style of building has deep roots in the Berber traditions of North Africa. Some historians compare these villages to settlements in the Atlas Mountains of Morocco. The resemblance is easy to see from a distance.

The history of the Alpujarra also includes a hard chapter. After the Christian conquest of Granada in 1492, many Muslims stayed in these mountains. They were later forced to convert, and became known as Moriscos. In 1568, they rose up in a long and violent revolt. When the rebellion ended, the Moriscos were expelled from the region. Settlers from other parts of Spain came to take their place. Yet the terraces and channels remained, and the new farmers kept using them.

Now, a name you may hear often. Mulhacén takes its name from a Nasrid ruler of Granada, known in Spanish as Muley Hacén. The Nasrids were the last Muslim dynasty in Spain, the family that built much of the Alhambra palace. According to a popular legend, the sultan was buried on the summit of the mountain, so no one could disturb his rest. There is no proof of this. But the story has stayed with the peak for centuries.

Here is a second surprise, and it belongs to Yegen, one of the villages in this very municipality. In the 1920s, a young English writer named Gerald Brenan came to live there. He later wrote a book called South from Granada, about daily life in the Alpujarra. The book describes village customs, festivals, and the hard mountain work of that time. Many English readers first learned about this valley through his pages. Some visitors still come here because of that book.

Look up again, toward the high ground. The upper zone of the park is a world of rock, scree, and cold lakes. Life there is hard, but it is special. The Sierra Nevada holds many plant species that grow nowhere else on Earth. They survived here because the high summits are like islands of cold climate in the warm south. Botanists come from far away to study them. In early summer, small flowers appear between the stones.

Animals live here too. The most visible is the Iberian ibex, a wild mountain goat with curved horns. Ibex move easily across steep rock, and they sometimes come close to hiking paths. You may also see birds of prey turning slowly above the ridges. In the lower woods, oak and chestnut trees give shade, and in autumn the chestnut leaves turn gold and brown. Each altitude has its own season, so the landscape changes as you climb.

The northern side of the range feels very different. There, facing Granada, you find a ski resort, cable cars, and roads climbing high. The southern side, where you are now, is quieter. Paths connect village to village, and many follow old mule tracks. Walkers can move from one settlement to the next in a day. The pace is slow, and that is the point. Nothing here asks you to hurry.

Before you move on, take a moment to look at the scene in front of you. Find a terrace wall, a channel of water, or a chimney on a nearby roof. Each of these exists because of the mountain behind it. The snow on the summit becomes the water in the channel. The water becomes the vegetables in the field. As you walk away, listen again for that sound of running water... it has come a long way down to reach you.
