Is it worth going up the towers for a visit to Segrada Familia Basilica in Barcelona?
I went up to the tower, if you buy the tickets online its only a couple euros extra, and I really enjoyed it. Not only is the view amazing, but you also get to experience the architecture from the inside. I dont think that it is necessary in order to enjoy the Sagrada Familia but I think it was a bonus. There are many places in Barcelona where you can get an incredible view, but being in the tower of the Sagrada Familia was a fun experience and worth the couple extra euros for me. It also depends how much time you want to spend there, I dedicated a solid half of a day to explore the area and the church.
