The total solar eclipse will be visible from parts of Spain for the first time in more than 120 years and is expected to attract numerous visitors from both Spain and abroad. Along the so-called path of totality, municipalities, cities and tourism organisations are already making intensive preparations for the event.
Spain prepares for a once-in-a-century event
The solar eclipse on 12 August 2026 will be one of the most significant astronomical events in Europe. The Moon’s shadow will pass over several regions of Spain, creating a unique viewing opportunity: for a brief period, the Sun will be completely covered by the Moon, causing the sky to become noticeably darker in the middle of the day.
The path of totality will pass through parts of Galicia, Asturias, Cantabria, Castile and León, La Rioja, the Basque Country, Castile-La Mancha, Aragón, Catalonia and the north of the Valencia region. The Balearic Islands will also be able to witness the eclipse shortly before sunset.
For many regions, the event is not only an astronomical highlight but also an opportunity for tourism. Numerous municipalities are planning events, public viewing locations and scientific activities centred around the solar eclipse.
Two million free solar eclipse glasses
A key part of the preparations is ensuring public safety. For this reason, the Spanish government and the ONCE organisation are launching a major distribution campaign: a total of two million certified solar eclipse glasses will be handed out free of charge.
Of these, ONCE will distribute around 1.7 million pairs, while a further 300,000 glasses will be provided through the Spanish Foundation for Science and Technology (FECYT) to scientific institutions, museums and public organisations. The campaign is being carried out under the slogan “Una vista única. Cuídala” (“A unique view. Protect it”).
The aim is to protect as many people as possible from unsafe viewing methods while ensuring that everyone interested has the opportunity to experience the event safely.
Where can visitors and residents get free glasses?
In numerous regions across Spain, preparations are already underway for the distribution of free solar eclipse glasses. Madrid is taking part in the nationwide initiative and is distributing the protective glasses through public institutions including the Madrid Planetarium, the History Museum, the Museo de San Isidro, the Conde Duque Cultural Centre and various municipal libraries.
Asturias is particularly well prepared, as one of the regions offering some of the best viewing conditions. More than 50,000 certified glasses have already been distributed through town halls and tourism offices.
Catalonia is also planning a large-scale distribution of around 150,000 pairs at official viewing locations, while in Valencia, protective glasses will be available through various public institutions and programmes such as València Sostenible.
In Galicia, the glasses are being distributed in some cases through regional newspapers, which are including them with their editions. In addition, regions such as Aragón, La Rioja and Castile and León are organising their own distribution campaigns, with many areas handing out the glasses through local councils, tourism offices and public events.
Why ordinary sunglasses are not sufficient
Experts are issuing strong warnings against looking at the Sun during the partial phase of the eclipse without proper protection. Ordinary sunglasses do not provide sufficient protection from intense solar radiation and can lead to serious damage to the retina.
For safe viewing, only specially designed solar eclipse glasses that comply with the ISO 12312-2 standard should be used. Damaged or scratched glasses should no longer be used.
Using cameras, binoculars or telescopes without special solar filters is particularly dangerous. These optical devices can concentrate the Sun’s radiation and cause serious eye injuries as a result.
Spain expects millions of visitors
The solar eclipse could become a major tourism event for many regions of Spain. Rural areas along the path of totality are particularly hoping for additional visitors, as they often offer ideal viewing conditions with low levels of light pollution.
Astronomy enthusiasts from across Europe are already planning trips to Spain to experience this rare event. Municipalities are preparing accommodation options, events and dedicated viewing areas for visitors.
A summer full of astronomical events
The 2026 solar eclipse marks the beginning of an extraordinary series of astronomical events in Spain. In the years ahead, further spectacular celestial phenomena are set to follow, including an annular solar eclipse in 2028.
For Spain, this marks the beginning of a very special summer: millions of people will experience together how daylight transforms for a few minutes into an extraordinary astronomical spectacle.
