1. Montserrat, Spain
From the mountainside monastery to the 'stairway to heaven', the sights of Montserrat are incredible and start well before you reach the town. Whether you choose to take the cable car or the rack-train to ascend the mountain, you can be sure of a breathtaking panorama.
This holy town holds many religious artifacts and a ton of French art that spans centuries, featuring works by El Greco, Monet, Dali and more. It's also a site of pilgrimage, with visitors coming from far and wide to visit the statue of the Black Virgin, rumoured to have healing properties.
Fan of hiking? Catch the Funicular de Sant Joan, which takes you further up the mountain to the hiking trails that lead to the tallest peaks.
