Flowers in Park Güell, Barcelona. Park Güell is a park in the western part of Barcelona and was largely designed by the architect Antoni Gaudí. Some of the surrounding park is free with lovely views over the Barcelona skyline, but most of the section containing Gaudí’s work requires payment and in the high tourist season you may need to purchase the ticket ahead of time and stand in a queue to even enter. I confess to being a bit underwhelmed by the paid section. Visiting the area is worth it and I found the surrounding park and neighbourhood of more interest. Gaudí’s architecture within Barcelona is a better bet on time well spent on Gaudí stuff in my opinion.
You can reach the park via public transport but the station does not go right to the park and you must walk through neighbourhoods and significantly uphill to reach the park. If you chose to go I would make it a half-day or a day trip. Plan to spend some time in the regular park as well as some of the neighbourhood eateries as this will give you more to see and do, as well as allowing you to cool off from the heat and contribute to the local economy.
