You can travel to West Algarve via flights to Faro or Lisbon, or by train and bus.
(e.g. via Paris, train to Bordeaux, Flixbus to Lisbon; or via Hendaye/Irun, and Madrid; or via Barcelona and Madrid)
In Portugal, there are trains (cp.pt) and buses (rede-expressos.pt), to get to Aljezur.
From Faro, take the bus 16 to the train station, take the train to Lagos, and then the bus to Aljezur. From Lissabon, there is a direct bus to Aljezur. Faro is closer nevertheless.
Note: You will be responsible for your own transportation on site (some of the workshops are not on the Finca, but e.g. on different beaches or in the mountains). A doodle group will be available, where you can coordinate carsharing with other participants, also for the Holidays (if you come before or stay longer). The link to the doodle group will come via Email with the confirmation of your registration.
By experience the cost of carsharing is 6-8€ per person/day, depending on the car and if needs to be hired, respectively if you arrange for airport transfer.
