Wonderful tour! - We had a wonderful experience on our tour. We were travelling with two small children and Angela and her team were very accommodating and warm!

Great Afternoon - Wonderful afternoon saw some incredible sites. Company was great to work with. We had specific time frames and they were able to accommodate us.

Volcano cave story - Explanation of how the cave begun to form from lava bubble while cooling. Inspiring for all and not just for people intereseted in caves.

Beautiful experience - Very nice Tour Guide was really good informed about nature and landscape Enough time to enjoy the different sites Would recommend it!

A complete tour of the... - A complete tour of the most important underground points of the island of Terceira. No rush, in a nice atmosphere and lots of information about the Azores.

Unique and beautiful scenery - We had a great time on this tour. The caves we saw were absolutely amazing and well worth the visit, as they are very rare natural phenomena. Especially the 'Algar do Carvao' - it was beautiful, and such a unique place to see. The 'cathedral' is jaw-dropping. Our tour guide, Amelia, was great. While on the ride to see different places, she talked to us about the island, its history, and traditions. It was such a positive experience. I highly recommend taking this tour.

Underground Volcanic Tour - Guides enthusiasm, personality, expertise, and pride in her tour while expressing care and concern for her customers.

Awesome half day tour - Underground Van Tour - The entire Underground Van Tour with Azores Nature Tours was amazing. James was so knowlegable, kind and considerate. Lagoa da Pata or Duck Lake was beautiful and like a fairy-tale setting. However, Algar do Carvão was the highlight for me. Walking around inside one of only two volcanoes in the world that allows visitors was definitely an experience I will never forget! Besides being overwhelmingly huge it was also so magical. The different lava, the moss, the lagoon and the beautiful spaces created a truly breathtaking adventure. I would highly recommend this tour with Azores Nature Tours when you visit Terceira Island! Thank you James!!

Highly recommend - Guide was great! They were on time, clean vehicle, and the views fabulous. We saw two underground sites and one above ground, in addition to the vistas.

Impressive walk into the volcano - I was greeted very warmly by our guide Emilia. She accompanied us in a friendly and competent manner. The tour of the volcanic crater was particularly impressive. Another highlight were the tame chickens and ducks at the lagoon.
