Excellent Family Tour
This was a wonderful experience. We were picked up from the hotel by our guide Bernardo in a jeep. It was just me, my husband, and my 5 year old daughter. Bernardo was very personable and a wealth of information. We learned so much about the island, its history, and its culture. We never felt rushed and he was so good with our daughter. The caves are a must see if you are visiting the island. He also gave us several recommendations for restaurants and places to go with our daughter during our stay on the island. Strongly recommend booking!
Response from the operator: Thank you so much for your kind words, it is always a pleasure knowing we made your stay in Terceira a memorable one regards proislandtour team

100% Recommend!!!!!
Antonio was extremely knowledgeable about all thing Terciera. The history, flora, fauna and geological history. He was also fun, friendly and very accommodating. He offered to tailor the tour to whatever we wanted. The jeep was clean and comfortable. He picked us up exactly on time. We saw 2 volcano tubes, a volcano and sulfur pit (which is way more beautiful than it sounds). He also offered to reach out any time about anything terceira. I feel like we made a friend here.
Response from the operator: Thank you very much, it was a lot of fun touring with you, and yes i also feel like i made new friends, anything you need from Terceira if i can help let me know best regards António

An Education that Goes Beyond the Caves and Volcano tubes.
The different sites were each interesting in their own way. The “chimney” was beautiful. Beyond the caves, we learned about the history, culture, plant life, people, lifestyle, and more from our guide. We hadn’t even picked up the second family in our jeep and it already had felt like a full tour because of all that we learned from Bernardo. Bernardo was an outstanding tour guide. Not only was he constantly educating us and answering questions, he was clearly passionate about conservation and the caves. Great tour.
Response from the operator: Thank you so much it is always so nice to read that we added something special to your visit to our beautiful island of Terceira Best regards Proislandtour team

Response from the operator: Thank you very much, very happy you enjoyed. Regards Antonio

Why this scores 76
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Cave Tour in Terceira: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Terceira.
How much does Cave Tour in Terceira cost?
+
Prices start at $53 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Terceira usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Cave Tour in Terceira take?
+
Plan for about 3 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Terceira is not rushed.
Is Cave Tour in Terceira worth it?
+
It holds an Outty Ranking of 76 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 48 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Terceira, and how flexible the cancellation terms are.
Can I cancel or reschedule Cave Tour in Terceira?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Cave Tour in Terceira suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 3-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Cave Tour in Terceira?
+
Around 17 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Terceira can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Terceira and add a light layer if any part of the 3-hour experience runs outdoors or after sunset.
Where does Cave Tour in Terceira start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Terceira within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Terceira?
+
On Outty we rank every Terceira experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Terceira Island: Full Day Tour, Underground Van Tour (Half Day) | Terceira Island, Watching whales and dolphins on Terceira Island. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Terceira?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Terceira?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
