It's better to do the route by ebike. There's a lot of elevation gain.

"The Vall de Boi is a narrow valley, carved deep into the Catalan Pyrenees. More than 1,000 years ago, seven small villages emerged in the valley, which no one would remember if nine Romanesque churches hadn't been built at that time. The isolation has contributed to the fact that at least some of these churches have been preserved almost in their original state," says the website for the television series "Treasures of the World - Heritage of Humanity." Comprising several hundred episodes, the series (in German) presents special places from all continents and eras that – despite all their diversity – have one thing in common: They have been awarded the honorary title of World Heritage Site by UNESCO. The film about the VALL DE BOI with its Romanesque churches is available in the ARD media library under the following link => https://www.ardmediathek.de/video/schaetze-der-welt/vall-de-boi-spanien-folge-260/swr/Y3JpZDovL3N3ci5kZS82ODk4NDYw

The Romanesque church of Sant Feliu de Barruera dates from the 11th century, although the nave, the bell tower, two chapels and the portal were added in the 12th century. It is very interesting to compare the different architectural details according to the period in which they were built.
