Start your trip with a visit to Park Güell, a beautiful public park designed by Antoni Gaudí in the early 1900s. This park is a UNESCO World Heritage Site and features unique architecture, colorful mosaics, and stunning views of the city.
Next, visit the Sagrada Familia, a breathtaking basilica also designed by Gaudí. This masterpiece has been under construction for over 100 years and is still not yet complete, but offers a truly awe-inspiring experience. You can explore the interior and climb the towers for stunning views of the city.
End your trip with a visit to the Alhambra in Granada. This palace and fortress complex was built in the 13th century and features beautiful gardens, intricate architecture, and stunning views of the city and surrounding mountains.
If you have more time, consider visiting the Picasso Museum or the Gothic Quarter in Barcelona. If you have less time, skip the towers at Sagrada Familia which can have long lines. When visiting Alhambra, make sure to book tickets in advance and check for any scheduled maintenance that could impact your visit.
