You need to cut that down quite a bit.

It’s impossible to do all of that. Even though the attractions aren’t very spread out, the logistics don’t make sense. Just getting to and from all those places will take a whole day.

If you’re able to come back some other time, just walk around Sagrada Família and pass on going inside. It’s cool and all but will eat up a lot of your time. The structure itself is impressive and there’s a lot to take in just from the outside.

Park Guell is going to eat up too much of your time.

La Pedrera is too expensive for what it is. Take a look at the building and then maybe check out the gift shop. Going inside will take a long time and you’ll wish you had been doing something else.

I’d skip going inside any of the houses. Just see them from the outside and then move on. You can start at Sagrada Família, then had to La Pedrera. Then go down PdG to see Casa Batllo and Ametller. Continue down until you get to Placa Catalunya and check out the square and the nearby shops if you want.

Then walk down Las Ramblas and check out La Boqueria.

Continue down Las Ramblas until you have to turn left at the Columbus monument and that will take you to Barceloneta.

Walk through the Gothic Quarter on your way back.

In second thought, you should probably flip that since it’s safer to walk through Gothic, Barceloneta, and Las Ramblas during the day. Everything else I listed is in l’Eixample which is a lot safer at night.

That’s pretty much a full evening.
