Looking down on Barcelona
The city of Barcelona can be seen from specific locations such as the Columbus monument of 60 metres in height, the viewpoint of the Sagrada Familia, or the viewpoint of 360º of beautiful shopping center Las Arenas. There are even lesser known points too, like the Collserola Tower (with the whole city at your feet) or classics like the fabulous view from Park Guell.
Montjuïc - Where the Earth meets the Sea
One of the most popular viewpoints of the city is from Montjuïc. it is located around 200 metres above sea level and though it's quite a trek, you can see much of Barcelona, from the ports to the Collserola mountain range depending on where you are on the mountain. It's a great spot for both amateur and professional photographers. The viewpoint is accessible throughout the year.
If you love the idea of travelling on a cable car, then you can soar like a bird down to the mediterranean Port Vell from the mountain. See you favourite city in all of its colourful splendor!
The Maritime Port from a Helicopter
Close to Montjuïc is the maritime port. From above you can see the trails left behind the boats during a helicopter flight. The take-off and landing take place close to the port. Going higher and higher, Barcelona transforms more and more into a toy set, with little cars buzzing around the square blocks and the deep blue sea reflecting the sun... It's stunning.
The Ferris Wheel of Tibidabo
Another option to enjoy panoramas of Barcelona is to go up to Tibidabo as part of a day trip to Collserola. The veteran funicular is over a century old nad can still be found in a good state. The top is a marvel and includes some of the main points of interest in the city - The Templo Expiatorio del Sagrado Corazón and Collserola Tower
Get a ticket for the theme park and take a ride on the Ferris Wheel. You will "float" above Barcelona, admiring both the natural and urban beauty.
There are other great viewpoints in uptown Barcelona and you can take a look at those in this guide to the northern part of the city.
Go up the Columbus Monument
Much easier (and cheaper than a helicopter) is to visit the Columbus Monument. No, you don't have to get out the climbing equipment, because there is a life that will take you right to the top. It runs during the summer months every day until 9pm.
See the City of Gaudí from the Sagrada Familia
What is Barcelona without Gaudí? One of his most famous works is without a doubt the Sagrada Familia. The basilica is a wonder in itself if you take the time to slowly process and understand Gaudí and his work, but another wonder is the view that you are provided with open taking the lift up one of the towers. The long descent afterwards down the spiral staircase will give a sense of scaled of this beautiful cathedral. There's more information about scaling this building in this article
Park Güell Viewpoint
Park Güell was a massive effort for Gaudí to complete, and it's where you'll find his house-museum. The park creates a surprising blend between nature and man-made with multicolor mosaics and extravagant architecture. Its as if the entire park is a movie set (well it technically has been once). You can stroll through the park and full in love with its beautiful views in Barcelona up until 8PM.
Whether you're drifting in a cable car, flying in a helicopter, or strolling down the grand staircases of the Sagrada Familia. You'll probably end up regretting that you're not a bird but hey, in Barcelona you can certainly experience it like you were. :)
