Absolutely unforgettable experience with Adventure Antigua – Xtreme! Our island tour with Adventure Antigua – Xtreme was hands down the best way to experience Antigua in its entirety. From start to finish, it was exceptional. Desmon and Leslie were truly outstanding—so warm, kind, professional, and very knowledgeable. They didn’t just show us the island; they brought it to life with rich history, local insight, and stories that made every stop meaningful. The 360° views of the entire island were breathtaking and something we’ll never forget. The itinerary was perfectly curated. We loved stopping at Stingray City, where we spent time in the water with the stingrays—an unforgettable experience. From there, we headed to Green Island, where we enjoyed fantastic snorkeling, delicious lunch, refreshing drinks, and the most amazing homemade banana bread. Every detail felt thoughtful and relaxed. We stopped in English Harbor, which was such a wonderful way to experience that historic part of the island. Seeing the harbor and surrounding scenery added even more depth to the tour and truly rounded out the experience. The Pillars of Hercules was stunning and an amazing experience snorkeling in the area, and finally, ending the day at Rendezvous Bay Beach was perfect —crystal-clear water, beautiful scenery, and rum punch to toast an incredible day. This tour exceeded every expectation. If you want to truly see, feel, and understand Antigua, this is the tour to book. Highly recommended—without a doubt one of the highlights of our trip! 🌴🍹✨ Sami & Mirela

Captain Desmond and crew were fantastic! Skilled, personable and very knowledgeable about their island. Was one of our favorite activities from our 6 day visit. Saw 360 degrees of Antigua and its majestic beaches. Stingrays, snorkeling, lunch and final visit to Rendezvous Beach were superb. Hesitated booking due to cost but worth every penny. Everything from ease of booking, detailed coordination on departure, and the trip itself was 10/10.

We had a great time on our tour! The lunch was yummy! Our favorite part was floating in Rendezvous Beach! We loved meeting the stingrays too & snorkeling to the reef with us! We loved our crew was Desmond, Leslie & Mastiga (spelling?). I would highly recommend this tour to anyone looking for an exciting adventure to explore Antigua by boat!

It was beautiful exciting ride around the island! The captain and crew were outstanding!!! We stopped to snorkel, have lunch, and visit stingray city. One thing I would be sure people know is that the water can be very rough. If you are prone to seasickness, come prepared.

This was an incredible day out. The trip gives you a roundtrip of the island. We were pretty much the only group at Stingray City, which made it more special. The islands we stopped at were so picturesque and perfect for snorkeling. We saw turtles in Nelson’s Dockyard and learnt a lot across the day as we passed by in the boat. I will say that if you get seasick, the Atlantic can get quite choppy, so take some pills for seasickness and sit in the back of the boat, if you can. Day was 10/10 – I absolutely loved it.

We really enjoyed this trip. The hosts were friendly and knowledgeable. The boat was smaller - they call it a speed boat, I'm not sure about that. There was less people - but we spent an hour picking up other people. The lunch provided was delicious and they do accommodate allergies - I'm celiac. For the both of us - for this day trip was $530 USD. We were only going to do one excursion so we figure we would pay the money and see all the things. We stopped to go snorkeling twice , went to stingray city, English harbour, and a couple of beaches. Like I said the trip was really great, but for the money - it was expensive!

Excellent itinerary, guides, food, drink and experience. The three guides provided us with one of the best experiences we have ever had on an excursion. They were happy, friendly, and super interactive. We were picked up and dropped off right beside our Virgin Voyages ship.
