Visiting Montserrat with Juan was a great experience! Juan was cheerful and very focused on ensuring that we enjoyed the trip. He picked us up right at the hotel and drove us to/from Montserrat in a comfortable black Mercedes van. He had all the tickets pre-arranged, including for the train ride up to the monastery, and intentionally timed the visit so that we were able to hear the performance of the boys' choir. I would definitely recommend taking the short uphill hike to the cross overlook of the monastery for a better view of the site. While not something that you might spend a few hours going through a museum or learning about the location's history, the physical setting is beautiful and it is a worthwhile trip if you want to take a day break from walking throughout Barcelona city.
