I have to agree with some of the others who replied. Anything that Gaudi created is just amazing to look at. Parc Guell is almost unreal; it is like being in a fairytale with little gingerbread houses all around you. : ] I also would reccomend that you take the cable car up the moutain and have a look at the Palace. There is a beautiful view once you get to the top! Have fun!

in 3 days if you are well organised, you can see everything. but don´t miss the Mont Juic and olympic villa area, park guell, sagrada familia as weel (don´t enter. there´s nothing) and barcelonetta if you go in summer. the beach is great! Remember to buy a T10, where you combine metro, bus and trains. Enjoy and then let me know!

I think that you must visit the sagrada familia, parc güell, the ramblas, and casa milá, casa batlló and casa atmetlló (they are in the same street). I guess you can visit them with the tour bus. You should also go to see the cathedral and walk over those streets, I really like them. And if you have time you can relax a little in the beach or go to Santa maria del mar church! good luck in Barcelona!

The top 4: Sagrada Familia + Hospital de St. Pau Parc Güell Les Rambles + Barri Gòtic Montjuic + The Olimpic city

don't miss gaudi! parc guell is amazing, casa battlo as well, you can buy a bus tour that drops u off in all the hot spots, u can do it all in approximately 2 days!u must go to the gothic neighbourhood! if ur there in summer dont miss the beach...

I think most of the answers have captured everything - there is so much to see in Barcelona! It is one of my favorite cities in Europe.

Gaudi's unfinished church & the huge park he designed.

Sagrada Familia is imo not so amazing inside. You have to spend a lot of time (2 hours or more) getiing to the top to see nothing special. Hmm.. Gaudi Park for sure!:)

get the 2 day tour bus you get to see everything and you can get on and off when you see what you want, olympic stadium, barcelona fc, gaudi's park, lots more

Definitely Las Ramblas and see the Picasso Museum, Parque Guell, Barri Gotique and any of the clubs along the water after 3 a.m.

parc guell, sagrada familia,picasso and mirò museums and ramblas!

gaudi park dont miss it

U can visit Gaudi, Parc Guell, Sagrada Familia, and go shopping at Ramblas. Also see matador's show in Ramblas.

Take your pick from all these answers, there's so much to see- and it's easy to get around. BUT- be alert for pickpockets, we were not victims but know several who have been. Take care of your wallet.

Parc Güell, Sagrada Familia, Las Ramblas and surrounding area, Barri Gotic, Montjuic (with the Olympic Parc and the Fundación Miro), Museu Picasso

Sagrada Familia, Park Guell, Gaudi Sites, Picasso Museum, the Beach, and drink the national drink of Spain, Sangria! Just went 3 weeks ago and had a blast. For late night fun, try Bikini. We didn't get home until 4AM!

Take one morning/afternoon to walk down the Rambla: stop at palau de la Virreina (always good expositions), Boqueria market, plaza Reial, Colomb. DO NOT EAT OR DRINK ON THE RAMBLA, there are only tourists traps! Then walk up the Rambla, passeig de Gracia to visit some Gaudi's houses and Rambla de Catalunya for some shopping. I would have a second day visiting the Cathedral in Barrio Gotico, walk there, the la Ribeira, the Born area with a nap in the Ciutadella Park. Finish the second day on Barceloneta beach. Good paella in the neighborhood. Third day, go walking in the Park Guëll and up to the Sagrada Familia. Evening near the Rambla del Raval.

park guell from gaudi, ramblas, sagrada familia

Sagrada Familia is a must!!! Anything Gaudi, Miro,and Montjuic is also worth the trip. Las Ramblas is great at night!

Definitely Sagrada Familia, Parc Guell, Las Ramblas (and the old market La Boucceria), and the Old Quarter (where you can take a free walking tour!! Most of all, have fun, relax and enjoy

GAUDI!!!

As much as possible, it will be exhausting but fun.

the church la sagra familia, the ramblas and the olympic city. if you want to go to the beach is not so bad for a great city like barcelona.

I think the best thing to do is take a 2 day pass on the hop-on, hop-off bus tour which will stop you in all the places of interest suggested above. Parc Guell is interesting and offers wonderful views, Sagrada Familia (although I don't think it's worth going inside), Casa Mila, and of course las Ramblas and the Barrio Gotico - try the restaurant Quatre Gats or go to the Ovella Negra (an ancient underground watering hole). Also if you happen to be there on a weekend, there is a spectacular fountain light and sound show (magic fountains) in front of the National Museum of Catalunya (you'll pass by it on the tour). Also for a good night club you can go on Montjuic to Poble Espanol (which by day is a miniature Spanish village museum, but by night becomes a club). Also if you want nice panoramic views of the city and the water, you may want to consider taking the blue trolley up to Tibidabo - there's a fun little amusement park up there to. Anyway...enjoy:)

For sure you have to visit the following places of interest when you are in Barcelona: * La Sagrada Família * Montjuïc * Neu Camp and FC Barcelona Museum (if you like soccer) * The Ramblas * The Olympic Village * The Music Fountains (in the evening) * Maremagnum

PARK GUELL, SAGRADA FAMILIA (climb up the tower), check out casa milo (get inside, its not cheap but worth it) und casa battlo. if palacio guell is done renovating, get inside too

you should see, PARK GUELL, SAGRADA FAMILIA, LA BOCCERIA which is a market on LA RAMBLA and then just go to the beach, BARCELONETA its really tourist place maybe if you like a nudist place... you can go to POBLE NOU and then walk.. it takes 10 min. to the beach, have a nice time. BCN ITS A LOVELY CITY.

Walk down the ramblas to the harbour area,have lunch in one of the many bars,chillout. If you feel adventurous try the cable car over the harbour - Great views- visit the Sagra Famalia church,Fresh Market just off the Ramblas_
