Highly recommend!
Dec. 2020
If you are in Terceira and like a bit of adventure and enjoy off the beaten track activities I highly recommend you to do this tour with Juca. Juca is very knowledgable of the hidden gems on the island and passionate about his work. Also, he makes sure you are safe while visiting the caves. Last but not least, he is passionate about photography and thus, he will take take some really nice shots of you. This was one of the best tours have done so far!

If your in Terceira do this
I looked this up and booked it my girlfriend only knew we were gonna see some caves. Oh boy were we wrong its so much more then just a Cave tour Juca knows so much about the terrain and the caves and takes his time explaining it to you al the while he waits for moments to shoot amazing pictures with your camera or phone and shows you how to do it yourself. All i can say if you have the chance to go on a trip with these amazing people then do it.

Best tour!!!
The tour was definitely one of the highlights of our vacation! Not only did Juca show us amazing caves and other great spots on the island, he also took beautiful pictures of us and told us so much about the island. And all the time you could feel his passion for what he is doing. This was definitely the best touristic tour we ever took anywhere. Thank you Juca!

Worth it!
An incredible day! We were a little leery at the amount of money for a day of seeing a few caves. What we didn’t realize is that 1. Juca has access to caves that we wouldn’t have ever been able to see or have even known about that were AMAZING. And 2. He is an amazing photographer that will take his own camera and/or show you how to use yours to create priceless memories of your experiences! Well worth the price and Juca really makes the entire day all about you and what you want to do/see.

Beautiful island, great guide, great birthday
Jan. 2020
Juca took me around the island and made sure to get lots of great photos of me. Even took me on a small hike to a waterfall. Volcano was stunning, lunch was amazing and we stopped to see a few other random things (black forest, lighthouse etc). Overall it was a great experience and it was nice that they will book only one person (most are a minimum of 2 people and I was solo traveling so that was important). Highly recommend.

Juka is a perfect guide and a very, very friendly person. His knowledge about the island and the caves is very impressive. He knows all 79 caves and has exploit some of them first. We enjoyed very much the tour, a combination of sightseeing, photo class and visiting a natural cave he has chosen. Juka immediately understood after having picked us up at the cruise ship that we wouldn’t be fit enough for all day underground tour. He changed the program immediately and gave us a wonderful tour and an unbelievable experience. His talent as photograph is really amazing as well. We learnt a lot useful tricks how zu use the mobile cameras best.

All in all a great experience we heavily recommend. Best value for money.

A grand adventure above and below ground!
Oct. 2019
This was by far the best tour we've taken, not just in the Azores, but in all of our travels. Marisa is an excellent coordinator, and reached out to us immediately after scheduling and again after we'd arrived in the Azores to confirm details. She also advised us to switch tour days when one of the sites we were interested in visiting was going to be closed on the day we'd originally scheduled our underground tour. This courtesy ensured we didn't miss one of the island's highlights- the volcano.

On the day of the tour, Juca picked us up bright and early, and took us to begin the tour in three caves that are not widely known. We also went to the more touristic sites. Juca is an expert spelunker, a renaissance man with expertise in photography and archaeology, and a knowledgeable, kind, and entertaining guide. We learned a great deal about the history of the island, the geological formations, and lots of other topics. Exploring the caves and taking beautiful photographs inside and around them was fascinating. We learned so much about lighting and camera techniques while also discovering hidden worlds. It was tremendous fun.

Juca also took us to a fantastic restaurant for a traditional lunch. We enjoyed visiting the kitchen and selecting the fish they cooked for us. Juca was also kind enough to take us to several above-ground destinations around the island, ensuring we could enjoy those sites as well as the caves. So many of the beautiful places he took us were off the beaten track, and we would never have known to visit them without him!

Capping the tour off with ice cream was the perfect end to a wonderful day. When we got back to our hotel, we collapsed with wine and snacks and enjoyed poring over the many gorgeous photos from tour.

The next day, Juca and Marisa invited us to meet them when we visited them in their lovely hometown. It was wonderful to meet Marisa in person, and it was lovely relaxing and chatting at a beachfront restaurant. We were so surprised they'd want to spend their downtime hanging out with us. They really made us feel like family. I cannot imagine a better way to spend time in Terceira. I look forward to returning soon.

A Terceira Island MUST DO!!!!
Aug. 2019
TRILHAS is simply the BEST experience on Terceira Island!!! Marisa made the online booking experience incredibly easy and confirmed our tour the day before. We had only one day on the island, and Juca picked us up at the airport with a smile on his face ready to show us the beautiful vistas - inside some unique caves and an incredible volcano! We loved how personal the whole experience felt - no rush or crowds, just nature's beauty!!! Our pictures were beyond expectation thanks to Juca's expertise and knowledge. Throughout the full, private-day tour, Juca's energy and passion are simply infectious. We simply fell in love with the island thanks for Juca and Marisa!

Best tour with THE best guide!
Aug. 2019 • Friends
I don’t know where to even start with the compliments! Juca is an incredible guide and moreover an even better person! My sister and me had a blast on the tour. Juca was very knowledgeable, experienced, helpful, passionate and nice. He combined his skills, what from photography, what from nature knowledge to make the tour suit us best and to make us feel as happy as possible. You definitely feel as if you’re his friend from the moment you step into his van. After having a great adventure day, he got out of his way to help my sister and me with a problem we faced. We got to meet his awesome wife Marisa and the wonderful daughter Carlota. I cannot even describe how genuinely good this family is! Marisa is an absolutely amazing woman! She makes you instantly feel like family. It has been an utmost pleasure being with them and we are so grateful to have had the opportunity to meet such wonderful people! If only there were more people like them in the world.
I highly highly recommend the tour with Juca, whichever tour you choose, I am sure you won’t regret it!
As for the whole family, again, a BIG thank you from the Croatian sisters! Hope to see you again in the future!:))

Absolutely fantastic!
Jul. 2019 • Couples
This was truly the best thing we did on our 6-week vacation through Spain, Portugal and the Azores. We were in Terceira for a week, and we were so lucky to find Juca and spend the day with him. He was hilarious, courteous, knowledgable, organized, friendly and all-around awesome.

He took us to a series of gorgeous caves not open to the public--caves that he and a team explored and mapped (have him tell you the story!). He kept us fascinated with his knowledge of the history, biology, archaeology and geology of the area (we're still reeling about the idea that Phoenicians could have been the first people on Terceira). Juca's also a professional photographer, so he took some amazing shots of us with his fancy camera. While he took us to rarely-visited places off the beaten track, he made sure that we saw the volcano, a more touristy spot, because he said was not to be missed, He also customized our day with a hike to a waterfall, then natural swimming pools, which we had all to ourselves. And he took us to the best restaurant for lunch, where we ate the most delicious meal we've ever had. That is not an exaggeration. The next day, we walked over 2 hours to get back to the restaurant to repeat the experience. No joke.

At the end of our day, he invited us to a bullfight party at his home a few days later, where we met wonderful fellow travelers, ate delicious local food (SO. MUCH. FOOD.), drank plenty of beer, partied with his wonderful family and friends, and were treated to live music by one of the most well-known festa performers in Terceira. Truly authentic, amazing experience.

Not to be missed. Worth every penny. Thank you, Juca and Marisa!
