I have one day I'd like to go out of Barcelona and return at the end of the day because we're going to Amsterdam the next day.
I'm not sure where the day trip should be. They all sound great! Monserrat, Figueras (Dali Museum), Cadaques (Dali house) are the choices. I don't know if you can do the Dali House and Museum in the same day or is Monserrat a better experience overall.
When I travelled to Paris, I wondered if we could do Versailles and Chartres in the same day trip. We ended up having enough time to do both on different days, but it would be possible if you were willing to go at 100% from early morning to late night.
I'd like to hear recommendations and you think would be best. Thanks!
