I traveled to Spain about a year ago with my daughter. She'd served her mission there in Barcelona and we went back. Beautiful country, beautiful cities. We visited Madrid, Valencia, Barcelona, Monterrey, went out to Las Palmas, went up to Andorra. Just a lot to see and a lot to do. I highly recommend it.
My favorite place to visit in Spain was San Sebastian. It's this little beach town in the Basque country of Spain. So it's just really charming, really cute, very chill vibes, and really good food. They have pinchos, which are like tapas, so like small little dishes that you eat. And then they're famous for Basque cheesecake, which is the most delicious thing you'll ever eat.
If you travel to Barcelona in Spain make sure you go to the Sagrada Familia and to Park Güell and the Gaudi house. A lot of fun but heads up make sure you schedule and buy tickets before you show up there. You will need them to get in. In the Valencia area in Spain they have beautiful beaches. I highly recommend spending a day at the beach and just taking all of that in.
Spain, especially like in the city of Barcelona, or in the islands, or in the south of Spain, you know, there are so many amazing things that people pay millions of dollars to go see every year. And just like, there's so many old sites you can see, so many historic buildings, so many pretty views.
