Was very happy with our half day tour of Montserrat. Could have very easily done a full day. Didn't have enough time to see everything thoroughly. Very beautiful. Loved the museum and the Basilica is beautiful (although very crowded). Recommend this tour. The tour operator was fairly easy to find in Barcelona. If you have a full day do the full day tour. Guide and driver did a great job. Enjoyable for kids as well as adults.
