I am planning a day trip from Barcelona to several of the towns and villages of the Costa Brava. We are not interested in renting a car, and would consider a small tour 4-10 people. I also found a transportation service/tour from Barcelona to the Costa Brava called "Welcome Pickups". This tour includes Girona which we have visited on a previous trip to Spain and as much as we enjoyed our visit to Girona, this time we would like to spend the day along the coast [see below]. I've read the road that links the towns of the Costa Brava is not for the faint-at-heart, or those prone to motion sickness, plus is not driveable except by locals. It appears that to reach some of the places I list below, a vehicle would have to make a series of loops to/from the coast to/from the main road [ C35?]. Is this correct?
I noted on a map there is a train route that runs along the coastline from Barcelona to Blanes. but then turns inland and does not reach Tossa del Mar, Sant Feliu deGuixo, Platja d'Aro, Calella de Palafrugell, Tamariuls, Llafranc, and others. Is this a passenger route and if so, how frequently do the trains run? Is there some type of rail-pass/ticket we could purchase to, in effect, hop off and hop on the train along the route from Barcelona to Blanes?
Additionally, what are the chances of finding a transportation service in Blane that could extend our visit to Tossa del Mar and some of the other towns noted. We have all day for the round trip.
