Hey I'm Patt, right here goes hehe, which ryan air airport are you flying to girona or reus? reus would be the best, from here you can get a bus from outside the terminal, they fit in with the flight times, this will take you to Barcelona sants the main train station, from here you need to take the manressa-terrasa train and get off in sabadell. There are 3 train stations in sabadell south central and north, so it depends where you are going to stay. Hotel Sabadell and hotel Urpi are the closest to the park. for these got to sabadell north and when you come up from the underpass, you need the exit on the roundabout directly opposite you, this goes downhill, follow it down and you will see the hotels. This time round we needed a room for 3 people so we stayed at hotel husa Valles this is a bit futher from the park, about 10 minutes by bike/foot. for this one go to sabadell north, then take the number 9 or 7 bus and it will take you straight to the hotel and only costs 1euro 25c. or there is usually taxis outside. If you can try and go with easy jet to BCN El Prat airport it is the closest and cheapest. you can take a train from here to sants again then take the manressa- terrasa train again. The park is good for a few days, you have to be creative, but there are many more places to ride, if your into street i recomend terrasa and for natural barcelona coast or torredembarra. If you need any more info just ask. I should be going back about that time again so maybe see you there.
