Meet your driver at your accommodation in Angra do Heroísmo, Praia da Vitoria, or Lajes, and start your half-day tour in an air-conditioned minivan. Explore Algar do Carvão, an empty volcano and its caves with remarkable unique mineralogical characteristics. The 90-meter-deep volcanic chimney formed approximately 3,200 years ago after the magma drained from the main chimney receding to the magma chamber. Next up is Furnas do Enxofre. Walk around a fumaroles field and see sulfur gas coming out from the ground. Contemplate the beautiful natural swimming pool at Biscoitos, surrounded by black lava and with a few colorful fishing boats anchored alongside. Stop for a photo opportunity in Miradouro do Raminho and see 3 islands. Finish a wonderful day with a handmade delicious cheese tasting.
