Well Ill just go ahead and for sure reccomend Buenos Aires if you like food, music, art, culture etc etc.
While in BA I reccomend seeing:
Calle Florida ( Florida street)- tons of crazy shops, impromptu tango shows, and the “Galerias Pacifico” which is a mall located on that street which is out of this world with architecture and interior design + amazing stores.
Casa Rosada– if you haven’t already seen the movie “Evita” I recommend it for a little history plus you get to see Madonna at the “pink house” lol. The big cobblestone area that is centered around the house is called ” Plaza de Mayo” which is where a lot of activism takes place ( which you may very well see- they are super politcal/social) and little peanut stands and memrobelia. Heres a pic I took somewhat recently
San Telmo– Great for craft shows, art fairs and more of local people doing there thing.
Boca– probably one of the most cultural places. Houses are painted bright and vibrant colors. Home of the Boca Juniors soccer stadium- which is like the life blood of Argentina ( soccer) The typical shops, cafes, and art stands.
The Zoo– I know every town has a zoo, but I always think its fun to see all the crazy animals. A lot of rabbits, birds and creatures are just let to roam around, so there are some good photo ops.
Now if your into architecture or history there are some awesome Cathedrals, theatres ( colon) , and monuments to check out ( obliesk, San Martin, the tower). The Recoleta Cemetery is also a sight to see ( Eva peron and other notables are buried there ) There are also bus tours ( i have done several) where you get to see alot of the popular things, plus they let you get off at destinations for time to explore and pick you back up.
We have a place off of avenue “Sante Fe” which is like the modern ” time square” like place of cafes, restaurants, boutiques and more posh type stores. So if that’s something you enjoy, its worth seeing too.
Theres also some obscure and fun things like a planetarium, a Japanese garden and some botanical type things too.
Any more specifics or what not, feel free to message me!
