Best Teceira Tour/photo shoot

I recently experienced a photo shoot/tour with Juca and I cannot recommend it enough! He was so friendly and accommodating. He is very knowledgeable about the island history, locations and features. He is also very helpful about advice on things to explore on your own. You should definitely book an adventure with him on your next trip!

Thank you so much for your words. We really appreciate your opinion! It was and always will be a great pleasure to have you with us, my friends! Hope to see you soon! Huge hug. Marisa & Juca

Unforgettable!

From the moment we started hiking across a farmers field towards our first lava tube of the day, we knew we were in for a unique experience, and our guide Juca delivered in spades! Expertly bringing to life what we were seeing, Juca made our experience informative and fun. Patiently answering our questions, captivating us with stories about island history and culture. The Algar de Carveo had recently reopened so we were able to spend some quality time in this spectacular volcanic vent also. We ended our very full day exhausted, dirty, and absolutely happy! We would do this tour again in a heartbeat. Thank you Juca for an unforgettable day!

Professional and Respectful

Regarding Underground Experience. Juca arrived promptly greeted us and proffesionally discussed the activities for the day and made sure we were prepared. Juca was very kind and checked in regularly to make sure we were comfortable with every aspect of the excursion. There were no surprises. He was up front about what was covered in the excursion, what we needed to cover separately (food,snacks and entrance fees to certain locations). The reason I chose Juca was because he has built relationships with private landowners to access private caves, he is an experienced cave explorer and is a proffeaional guide with insurance and integrity. Side note I do a lot of solo trips and would highly recommend Azores Expeditions to females traveling Solo.

Juca review

Juca was outstanding. I suspect that my review will be very similar to others. He picked us up, very punctually- at our hotel and greeted us with a wonderful smile and strong handshake while courteously reminding us of proper footwear for the adventure. His car was very clean and he was very conscious of safety. In planning our tour it initially was for just caves only, but Juca was very accommodating and we pivoted into doing an island tour. We visited many wonderful places, including great vistas, mysterious caves and the inside of a volcano. Luck has it that Juca is a professional photographer and showed us some of his tips and tricks while providing a few gem pictures. Lunch was at Canetas. Be sure to follow his recommendations and try the french fries which were out of this world. Juca is perfect for this job as he is extremely informative and pleasantly friendly. My wife and I have tremendous memories of the island and he made things so much better. It’s funny, we found ourselves mentioning his name when we were visiting other islands. That says a lot. Thanks John Carlos and keep up the great work !!!! Coleen and John

Best tour of Terceira

This tour with Juca was one of the best things someone could do on the island. My wife and I had a long layover on the island so decided to book this tour. Juca showed us so much of the island, told us all about its history, showed us some of the most stunning geography we have ever seen, and on top of it all is amazingly funny and a professional photographer so he helped us get some of our favorite photos from our trip. He and his wife graciously took care of us while our flight was delayed and overall are fantastic human beings, if you’re reading this, book this trip now you won’t regret it!

An adventure not to be missed - and a memory for a lifetime

We had an amazing day with Juca - mostly underground - on the island of Terceira. Juca has a ton of knowledge about the incredible, wondrous and fragile world underground, in caves and volcano’s. It really opened up our eyes to a mostly unknown world that is vital to the health of our planet. The trip was an adventure for sure - finding our way through caves that are not open to the public was an unreal experience. Juca does not only have a lot of geological knowledge, he is a gifted guide and made us feel safe during our entire expedition through sometimes narrow passage ways and over slippery rocks. We had a ton of fun, unexpected encounters with cows and descended into holes the ground in the middle of misty fields. After a great proper Portuguese lunch we went to the more commercial sites and the contrast could not have been bigger! Ending in the volcano was spectaculair. Juca is also a gifted photographer and he not only took some amazing pictures of us, he also taught us a trick or two about light and composition. All in all - a day not to be missed and definitely never to be forgotten!

You Won’t Regret It! An Unforgettable Experience!

I booked the all day cave tour. I only had one full day in Terceira. When Juca picked me up he asked if I wanted to do all day of caves or if I wanted to see more of the island. I chose to see more of the island. Juca and his wife operate the company and are very quick and responsive in inquiries. Juca does every tour and he is an awesome photographer who will take you to off the beaten path spots, along with popular spots at the right time to avoid crowds. I highly recommend this tour. If you are visiting the island for more than one day, book a multi day tour with them. I will be back some day and will spend several days with Azores Expeditions Thank you for an an amazing visit Azores Expeditions.

Amazing experience

We enjoyed the underground and photo tours; the service was perfect and excellent!! Juca is friendly, and he has incredible knowledge about each fantastic place. He knows the places perfectly and explains each detail to be safe, enjoy nature, and take amazing photos. We can appreciate nature very well; Terceira is the most beautiful and unreal place.

Unforgetable and joyful experience!

We visited Terceira in October 2023 and did the Underground Expedition with Juca. It was an incredible experience for us! Besides visiting a cave and a volcano, we also went into a cave not open to the public. Juca took as to a traditional Azorean restaurant, where we had a great lunch and met very friendly locals. Juca is very passionate in his profession and he has a great humor. We could learn a lot about the history and the geology of caves and volcanoes and also about Terceira and the locals from him. Thank you for this unforgetable experience! :) When we visit Terceira again, we will definitely do the other Tours with Juca. Simon & Daniela

Wonderful tour and fantastic guide!

Our family had an incredible tour with Juca! He has tremendous knowledge, enthusiasm, generosity and is a truly gifted photographer. The private tour surpassed our expectations - allowing us to experience private caves and other parts of the island we wouldn't have seen otherwise. And we had one of our best meals on the island. We will definitely book another adventure the next time we visit Terceira! Thank you so much, Juca and Marisa!
