The last time we were in Cadaques, we took the train from Barcelona-Sants to Figueres and the bus from Figueres to Cadaques (one hour). That's still an option for an upcoming return trip, but there are two others we're considering:
1. Bus from Terminal T1 at the airport direct to Cadaques (three and a half hours, but only one per day, we may miss it).
2. Train from Barcelona-Sants to Llanca, taxi (or Uber?) from Llanca to Cadaques.
Does anyone have any experience with either of these two alternatives, or recommendations from among the three options?
