We will be in Barcelona in late April and would like to take 1 day to see CADAQUES and GIRONA and BESALU. Its that feasible in 1 day ?
What are options of ways to see those places? I am hesitant to do it entirely on our own as I know there will be so much to see and some things need advance tickets ( DALI and Besulu baths)
Thanks in advance

No, it won't be possible in one day without a car (and hardly possible with a car if you don't want to be rushed and to spend less than 30 minutes in each location !).
Train from Barcelona to Girona is approx 1 hour, bus takes longer.
There is a bus from Girona to Olot which stops in Besalu
Timetable here : www.teisa-bus.com/web/horaris/L1.PDF
Cadaques is accessible by bus from Girona (count 2 hours):
Timetable www.sarbus.com
You can also take a bus from Barcelona bus station (Estacion del Nord) to Cadaques. See www.sarfa.com

I don't think you need advance tickets for Besalu baths - just show up at the time and place indicated by the Tourist office.

This isn't feasible if you're using public transportation. Even with a car it would be way too much, at least for me. Girona has plenty to keep me occupied for an entire day. Besalu can be visited in a couple of hours. Cadaques probably for a half day. The beauty of visiting these places is to have time to enjoy them and not run through them all.

You can check with one of the local tour/guide companies to see if they have anything that matches your wish list for a day-trip. It's posssible they may be able to arrange it, but such a trip (Barcelona-Girona-Cadaques-Besalú-Barcelona) will involve at least 5 hours on the road, leaving you much time to enjoy the visits.

Hi, This is Barcelona

You might want to pick just one spot for a nice day trip. Girona can be done on a easy day-trip by train.

You can also check Catalunya Turismo (www.gencat.cat/turistex_nou/home_ang.htm) to see what else you can do on a day-trip.

Thanks for the advice. We will opt for going to Girona for the day and save the others for our next trip!

You can click on my name to read my trip report from October 2010. We rented a car for a 3 night/4 day roadtrip: spent one night in Cadaques & 2 nights in Girona, & drove thru part of the Pyrenees, making a stop in Besalu, before returning to Barcelona. YOu definitely can't do what you want in one day. Can you do a 2 or 3 night roadtrip? If not, you have made a wise choice in going to Girona for a day. My trip report goes into detail of what we did for sightseeing in Girona & I name some restaurants we liked.
