Sierra Nevada Observatory

IRAM 30m telescope is a radio telescope, located in the Sierra Nevada mountain range, Spain. It is operated by the Institute for Radio Astronomy in the Millimetre Range (IRAM) for observing astronomical objects in the millimetre range of the electromagnetic spectrum. With its large surface and wide-angle camera, the telescope is capable of exploring large cosmic objects. It is one of the largest and most sensitive millimetre wavelength telescopes in the world, serving over 200 astronomers annually. The telescope is primarily used to study interstellar clouds, star birthplaces, galaxies, and black hole jets. Together with IRAM's second facility, the NOEMA observatory, the telescope is part of the global Event Horizon Telescope array. It was the only station in Europe to participate in the 2017 EHT observing campaign that produced the first image of a black hole.

Veleta (from the Arab word "Balata", meaning cliff) or Pico del Veleta is the third highest peak of the Iberian peninsula and the second highest of the Sierra Nevada. Its height is given variously as 3,394 metres (11,135 ft), 3,396 metres (11,142 ft) and 3,398 metres (11,148 ft).The mountain can be seen from the city of Granada. Veleta's northern slopes are home to the Sierra Nevada Ski Station. The access road that takes one to approximately 10 metres below the summit is the highest paved road in Europe across the mountains from Granada to the western Alpujarras. This road was built before the creation of the Sierra Nevada National Park in 1999. It has since been closed to general traffic beyond Hoya de la Mora, just above the ski station. However, the road is still used by ski station employees, national park rangers, observatory staff, cyclists and walkers, and a microbus service also takes hikers up to Posiciones del Veleta, a viewpoint 3,100 metres above sea level. In summer it is a relatively easy walk up to the summit from there. The Corral de la Veleta or Corral del Veleta glacier, at 37° N the southernmost glacier in Europe, disappeared in 1913.The IRAM 30m telescope is located on the slopes of Pico Veleta, at an elevation of 2920 m.

Mulhacén ([mulaˈθen]), with an elevation of 3,482 metres (11,424 ft), is the highest mountain in peninsular Spain and in all of the Iberian Peninsula. It is part of the Sierra Nevada range in the Penibaetic System. It is named after Abu'l-Hasan Ali, known as Muley Hacén in Spanish, the penultimate Muslim ruler of Granada in the 15th century who, according to legend, was buried on the summit of the mountain. Mulhacén is the highest peak in Southern Europe outside of the Alps. It is also the third-most prominent peak in Western Europe, after Mont Blanc and Mount Etna, and is ranked 64th in the world by prominence. The peak is not exceptionally dramatic in terms of steepness or local relief. The south flank of the mountain is gentle and presents no technical challenge, as is the case for the long west ridge. The shorter, somewhat steeper northeast ridge is slightly more technical. The north face of the mountain is much steeper and offers several routes involving moderately steep climbing on snow and ice (up to French grade AD) in the winter.Mulhacén can be climbed in a single day from the villages of either Capileira or Trevélez, but it is more common to spend a night at the mountain refuge at Poqueira, or in the bare shelter at Caldera to the west. Those making the ascent from Trevélez can also bivouac at the tarns to the northeast of the peak.

Alcazaba is a mountain in Spain. Standing at 3,369 m (11,053 ft), it is the third highest mountain of the Sierra Nevada range and the fifth in the Iberian Peninsula. The impressive north face can be seen from the town of Granada. The name Alcazaba derives from the word "fortification" in Arabic.

Sierra Nevada (Spanish: [ˈsjera neˈβaða]; meaning "snow-covered mountain range") is a mountain range in the Andalusian province of Granada in Spain. It contains the highest point of continental Spain: Mulhacén, at 3,479 metres (11,414 ft) above sea level. It is a popular tourist destination, as its high peaks make skiing possible in one of Europe's most southerly ski resorts, in an area along the Mediterranean Sea predominantly known for its high temperatures and abundant sunshine. At its foothills is found the city of Granada, and a little further south, Almería and Motril. Parts of the range have been included in the Sierra Nevada National Park. The range has also been declared a biosphere reserve. The Sierra Nevada Observatory and the IRAM radiotelescope are located on the northern slopes at an elevation of 2,800 metres (9,200 ft).

Güéjar Sierra is a village and municipality located in the province of Granada, Spain. According to the INE, it had a population of 2,988 at the start of 2010. The village is situated in the north-western part of the Sierra Nevada mountain range, at an altitude of 1,088 metres. The municipality borders Pinos Genil, Dúdar, Quéntar, La Peza, Lugros, Jérez del Marquesado, Trevélez, Capileira and Monachil. Its boundary with Trevélez and Capileira runs along the highest ridge of the Sierra Nevada, and over Mulhacén, making these the three highest municipalities in peninsular Spain. The Genil and Maitena rivers rise in Güéjar.

Capileira is the highest and most northerly of the three villages in the gorge of the Poqueira river in the La Alpujarra district of the province of Granada, in Spain. It is located at latitude 36° 57' N and longitude 3° 21' W, about 1 km north of Bubión. Its altitude is officially recorded as 1436 metres, though there is a considerable altitude difference between the oldest part of the village, which is at the lower, southern end, and the highest part, where tourist-oriented development is currently concentrated. The area of the municipality is 57 km². Although the Sierra Nevada Highway runs through Capileira and out across the Sierra Nevada towards the city of Granada, motor traffic is no longer permitted to continue across the mountains; Capileira is therefore the highest village that public traffic can reach, although you can continue to a car park where the national park begins and the road is barred to normal traffic. The national park runs a limited bus service on the now-closed road (reservations handled by office in the village) in summer. A track leads northwards from the village to the abandoned settlement of La Cebadilla, built to house the workers who developed the hydro-electric installation at the upper end of the Poqueira Gorge. Capileira has developed a significant tourist trade, acting as a centre for walking and for accessing the mountains especially Mulhacén, generally treated as a two-day climb from Capileira with an overnight stop at a mountain refuge en route. A bus route connects the village to Granada (via Lanjarón and Órgiva) and Alcútar (via Trevélez and Juviles); as of 2011 there were 3 services per day in each direction. The village has good facilities for visitors including a number of restaurants, a market on Saturdays, hotels and apartment blocks, but retains a typical Alpujarran character especially away from the main road. Its population in 2005 was recorded as 582 people, of whom 35 did not have Spanish nationality, most of them being citizens of other European Union countries. The village has a primary school but no secondary school.

Bubión is a village in Las Alpujarras region of Granada in Spain. It is located at latitude 36° 57' N, longitude 3° 21' W, at 1,350 metres above sea level. Its postal code is 18412. Together with Capileira (to the north) and Pampaneira (to the south) it has become a focus for the tourist trade in La Alpujarra, because of the spectacular location of the three villages on the gorge of the Río Poqueira and below the peaks of the Sierra Nevada. The three villages, with their characteristic Moorish features - narrow, winding streets, flat roofs - have been designated as a Conjunto Histórico Artístico, a region of special artistic and historical importance. Bubión is thought to have been founded in Roman times, and in any case it certainly antedates the Moorish invasion of the 7th century. Under the Moors, it was under the authority of Ugíjar. In the 16th century, after the fall of Granada to the "Catholic Monarchs", the village participated in the rebellions by the Moors (or "Moriscos" - Moors supposed to have been converted to Christianity). In the second rebellion, which started in December 1568, Bubión was one of the first villages of the Alpujarra to fall to the Catholic forces, after a major battle in the Poqueira valley. Following their defeat in 1571, almost all Moriscos were expelled from the province of Granada. They were partially replaced by Christian settlers from other parts of Spain. In the Spanish Civil War of 1936-39, Bubión and the other two villages of the Poqueira valley remained under Nationalist control, although Republican forces held the surrounding heights. The most prominent building is the village church, built in the 16th century and remodelled in the following century. It is a simple structure in the mudéjar style. In the census of 2001 Bubión's population was given as 610, consisting of 357 "residents" and 253 "non-residents" (i.e. with a home elsewhere). A substantial number of both categories did not hold Spanish nationality, the majority of them coming from other states of the European Union. The village had 170 tourist beds. The GR 7/E4 European long-distance footpath runs through Bubión. In addition a network of walking trails link the three white villages and the Poqueira Gorge, ascending into the Sierra Nevada and providing an approach to Mulhacén, the highest peak in continental Spain. Bubión is served by a bus route from the city of Granada through Órgiva, continuing up the Poqueira valley to Capileira; then on through Trevelez and some further villages. There are three buses a day in each direction by Alsina Graells plus an extra bus to Orgiva on market Thursday at 9 am. A limited service is available from Motril to Orgiva.

Canales Reservoir is a reservoir in Güéjar Sierra, province of Granada, Andalusia, Spain.

Pórtugos is a municipality in the province of Granada, Spain. As of 2010, it has a population of 401 inhabitants.

Trevélez is a village in the province of Granada, Spain. Its population in 2011 was estimated at 823. The river Trevélez flows through the village. They are located in the western part of the Alpujarras region. Two of the highest mountains in Spain, Mulhacén and Alcazaba, are just to the north of the village, a few hours' walk away. Located at a height of 1486 metres, Trevélez is not the highest recognised municipality in Spain. That honour goes to Valdelinares located in the Sierra de Gúdar range of the Sistema Ibérico, in the province of Teruel, Aragon, Spain. It lies at the confluence of the Río Trevélez with a smaller stream, to the southwest of Mulhacén, the highest peak of the Sierra Nevada and of the Iberian peninsula. The village lies to the west of the Río Trevélez. It is divided into three parts, the Barrios Bajo, Medio and Alto (lower, mid and upper quarters), with 200 metres of altitude difference between the highest and lowest points. The only bridge over the river is in the Barrio Bajo. The Barrio Bajo is a significant tourist centre, while the Barrios Medio and Alto are more typically Alpujarran in style, though tourism is important to the economy of the entire village. To the west, the nearest village is Busquístar; the road through the Bajo Barrio continues to the east and south to Juviles and Torvizcón. There is a regular bus service along this road, linking the village to the regional centres of Lanjarón and Órgiva as well as the provincial capital, Granada. Trevélez is famous for the quality of its air-cured hams, a speciality throughout the Alpujarras but particularly associated with the village, because the dry climate due to its altitude makes for ideal conditions for storing them. Trevélez celebrates the day of the Virgen de Las Nieves (Virgin of the Snows - see article in external links) in the summer months. On this day the virgin is carried to the summit of Mulhacén and a mass is celebrated. The traditional belief is that this will keep travellers safe in the Sierra Nevada for another year.

Pampaneira is a village located in the province of Granada, Spain. According to the 2005 census (INE), the village has a population of 355 inhabitants. It is one of three mountain villages of the Barranco de Poqueira in the Alpujarras region. The other two villages, Bubión and Capileira, are located higher in the Poqueira gorge. The Poqueira gorge starts below the mountain peak of Mulhacén, where the river Poqueira rises. There are many opportunities for hiking in the area. Guided walks are arranged by the local tourist offices which also sell mountain hiking equipment. Other companies can plan self-guided treks through the area. The nearest major town is Órgiva. One of the highest all year-round lived-in mountain village in Spain, Trevélez is located nearby in the mountains to the east of the three villages. Accommodation is available in all of the three villages but Capileira has the biggest range of facilities. At the north side opens the Sierra Nevada (Spain) range with one of the highest peaks in Spain ; Mulhacén and Alcazaba (Sierra Nevada). The village is located at about 1060 metres above sea level. There are many craft shops selling ceramics, leather and clothes. Also on offer are the locally produced specialities of cheese and ham. During the winter the Sierra Nevada and the Alpujarra mountains get covered in snow but the villages are rarely affected by snow for more than a few days a time. There are bus connections running every day from the town of Granada, Spain.
