Short answer
The Azores' famous pineapple plantations are mainly on São Miguel island, particularly in the Ponta Delgada area and the north coast. You can visit working plantations like Arruda Pineapple Plantation (Ananás dos Açores) and others in the municipality of Ponta Delgada. These greenhouses are open to tourists, offering guided tours and tastings. The best time to see the pineapples growing is during the warmer months, but visits are possible year-round. Check opening hours and tour availability directly with the plantations, as they may vary.
