Lots of nature indoors and outdoors - It was a great tour, even if the weather didn't play along. The sightseeing list included the Gruta do Natal, the Furnas do Enxofre fumarole field and an impromptu drive to a small lagoon. Algar do Carvão was unfortunately not a program item as it was still closed. Our guide had a lot to tell and we had a lot of fun.

Cave exploring off the beaten path - Bernardo picked us up promptly from our VRBO and gave us several options on our itinerary as it was raining. We saw things and learned about the island in ways that I would not have learned had we not taken this tour. Disappointed that the highlight cave was closed but we knew that in advance of booking. Highly recommend the tour and Bernardo

Very interesting! - An extremely interesting tour, Bernardo took us to some very evocative ‘secret’ caves. He was able to convey all his enthusiasm in explaining the island to us on a lovely afternoon (despite the adverse weather). Recommended!

A fun day at the Caves - It was a wonderful experience on this tour. Our guides Dora and Bernardo were knowledgable, enthusiastic and professional. We had a chance to interact with Dora, who drove the Jeep, is passionate about the island and its culture.
Note that the drive to the caves is in a jeep. If you sit in the back seat, be prepared by a bumpy ride on unpaved roads. Also the lava tube at Biscoitos may be demanding for those with restricted mobility. Other than that, it is great tour.

Amazing route with Dora! - We asked for tour in Spanish and were two people, so it was a private tour, so great! It is an entertaining and interesting experience, but Dora did it amazing!! He has great knowledge and tells everything in an exciting way, we had an amazing time, and he speaks super good Spanish! A charmer, he told us curiosities along the way about the island, customs, volcanoes... A total hit!!!

Spectacular Tour - Would highly recommend. - Antonio was our guide through Pro Island Tours. Absolutely amazing afternoon. My cousin and I enjoyed a personalised tour, especially tailored to our needs and interests. We saw things off the beaten track, that not many tourists get to see. Not crowded, beautiful and amazingly interesting. Also taken to an amazing lava tube - could not upload photos, but an astonishing experience. Antonio was a nice, gracious, friendly and knowledgeable host. I would thoroughly recommend this tour.
