Carolina was a excellent tour guide! Very knowledgeable and informative. She answered every question we threw at her. Also a genuinely kind and caring person. She is my top choice for Terceira tours.

If you're looking for an authentic, unforgettable experience in Terceira, Mario is your guy! We had the pleasure of being guided by him for three days, and we couldn’t have asked for a better host. Mario is absolutely in love with his island, and his passion is contagious. He doesn’t just show you the sights—he shares the history, the culture, and the stories that make Terceira so special. This is not your typical tour; it's a genuine, personal experience. Mario went above and beyond to accommodate all of our needs and made sure we felt comfortable and well taken care of throughout the trip. (WE WERE 12 PEOPLE) Plus, his Spotify playlist is top-notch—perfect for the scenic drives. But that's not all! Mario’s mother, who is just the sweetest, prepared delicious homemade meals for us that truly made us feel like part of the family. If you want to experience the real Terceira, do yourself a favor and book a tour with Mario. You won’t regret it!

Everything fine, Mario was a proficient guide who knows the island and its particularities quite well, and answered all my questions. I never felt rushed during the individual stops and visits. I enjoyed the trip.

Mario was a fantastic guide! He was so knowledgeable about the history, the geology and the locations of the caves. We also got to visit a beautiful overlook and natural swimming area in the ocean. He speaks perfect English and has a genuine love for the places we visited. We never felt rushed. He answered all of our questions in great detail. It was a wonderful afternoon!

The volcano was truly amazing. The cave tunnels and amount of history our guide told us especially about Nasa using it to test living conditions. It was a great day even with the rain sprinkle on and off.

I went with my family to visit Terceira Island and we chose Mário to take us to visit the caves and we couldn't have chosen better! One of the best guides we've ever had on our trips! From his friendliness and availability to his knowledge, not only of the caves but of the entire island. 10/10 I recommend it to everyone who wants to visit Terceira island
