This Gaudí-designed park isn’t just any old verdant space with trees. Park Güell is one of a kind, home to famous mosaic park benches, a whimsical “Gingerbread” house, and a massive, colorful lizard fountain. The park can get crowded, especially during peak times and dates, so to avoid the waits, consider a skip-the-line tour to see the park and learn about its unique history.

Barcelona's Unesco-listed Park Güell is where Antoni Gaudí turned his hand and imagination to landscape gardening. It’s a surreal, enchanting place where the great Modernista's passion for natural forms really took flight and the artificial almost seems more natural than the natural. The park, located in Barcelona, is extremely popular, and access to the central area is limited to 400 people every half-hour – book ahead online. The rest of the park is free and can be visited without booking.
