Looking to see Gaudi Architecture, Segrada Familia and The Pedrera and other highlights. Any tour groups that come highly recommeded. The pepitotours.com was recommended but they are not availble on September 1, 2024. I'm cross checking with Trip Advisor and Viator. Thanks
Runner Bean Tours has a good free walking tour of the outsides of all the Gaudi sites including Sagrada Familia. We took it in 2018 (also did the other free walking tour and the night time one) and I would highly recommend.
Echo the recommendation for Runner Bean tours. We participated in their Gothic Quarter walk this past May, and had a positive experience.
Another option, depending on what you're looking to see (and admittedly much pricier than RB), is a private guided tour with the company Barcelonina. They offer several itineraries; we took their Sagrada Familia and Park Güell 'combo' (https://www.barcelonina.com/en/tours/the-park-guell-and-the-sagrada-familia/) as we're fans of Antoni Gaudí and wanted to better understand what this artist left behind to his city.
