Do. Not. Miss. This.
The first total solar eclipse visible from mainland Europe since 1999, and if you are able to see totality in person, you absolutely must go see it. As someone who saw the 2024 totality in Cleveland, Ohio USA, I can confirm that your mind will melt in the best way.
The path of totality begins in far northern Siberia, sweeps through the Arctic and North Atlantic, passes over Iceland, and cuts across northern Spain before ending over the Mediterranean. Major Spanish cities in the path include A Coruña, Bilbao, Zaragoza, Valencia, and Palma (unfortunately Madrid and Barcelona fall just outside it). Check out the ESA link below to see the map and find your closest place.
The best views are going to be in Spain. Since totality is going to arrive about an hour before sunset, there's a chance to catch the "diamond ring" effect right at the horizon. Maximum totality lasts about 2 minutes and 18 seconds.
From the US, the northern tier of states from Alaska to parts of the mid-Atlantic will see a partial eclipse, though most will catch only a small bite taken out of the sun. If you're not traveling for totality, this one is still absolutely worth a livestream.
Join the ESA either in person at viewing sites or virtually during the event to get the best coverage: https://www.esa.int/Science_Exploration/Space_Science/Join_ESA_for_a_total_solar_eclipse_on_12_August_2026
