I visited Camp Nou with my boyfriend on his birthday. We booked a few weeks in advance, before the upcoming match was announced. Unfortunately, we had booked for the day before the match and so when we arrived we were told a lot of the stadium was closed. Of course, this was completely understandable and the staff were great, offering for us to come back the day after the match, allowing us to use our original tickets. This was greatly appreciated and we took them up on this offer.
Although the museum wasn’t amazing, it was informative and did contain a lot of interesting pieces. The stadium itself was wonderful, and it was great to see areas such as the common area, away changing rooms, and the commentators’ box - even if you’re not a football fan!
We paid an extra €5 each for the audio guides, which was worth doing. Photos are taken of you/your group at various points, which were available to buy at the end. However, as with all such attractions, these very quite expensive.
