ATLANTICOLINE

Atlanticoline, the Azores' main shipping company, operates a ferry service between Praia da Vitória and Graciosa, only from June to September. This line (the white one) also passes through São Jorge, Pico and Faial. For the rest of the year, Terceira is not connected to the other islands by boat, so you'll have to fly to get between them. Note that Atlanticoline operates a second line in summer (the purple one) from Angra do Heroísmo to Calheta, on São Jorge. For travellers who have the time and inclination to travel differently.
