Entrance to the park is free, and no tickets are needed. The park is open from 6:30 am to 8:00 pm every day. The park has several entrances, but the most popular one is located at the end of Carrer de la Sagrestia street. Another entrance is at the top of Avenida de Catalunya, a pedestrian street in Barcelona. These two entrances are connected by an escalator that takes you up to a platform above these two entrances. In the centre of the park is one of Gaudí's famous architectural masterpieces, Casa Vicens. This building is worth looking at when taking the Complete Park Guell Tour
Casa Vicens housed sculptures by Antoni Gaudí and his son Jaume, who is responsible for creating the magnificent stained glass windows on Casa Vicens. I asked the ticket person to tell me more about Casa Vicens, and they told me that it was one of the first houses that Gaudí designed after he moved to Barcelona in 1883. It became a private residence in 1903 and a museum and art gallery in 1975. Suppose you're going for a visit inside Casa Vicens. In that case, I highly recommend stopping by Sagrada Familia because it is only a couple of blocks away from this magnificent monument and you can buy La Sagrada Familia Tickets .
