We pride ourselves on designing and leading snorkeling trips of a lifetime, but ultimately our success is measured by how our clients feel about their experience…

Thank you so much for a wonderful trip as always. We had a great time and deeply appreciate your knowledge of the fabulous places you take us to.

Linda and I want to thank you both for making this a wonderful trip for us. We had a terrific time, learned a lot, and saw beautiful creatures and shared the company of many lovely people…
Richard Luduena, Texas, USA (Palau 2017)


Wonderful experiences on beautiful reefs teeming with life. Wonderful leaders and fun group of guests.
Barbara Lister, Colorado, USA (Palau 2017)


Glorious is the word, Lee. Every snorkel, the diversity of habitats, our wonderful snorkeling group and crew…Your cocktail hour presentations were so entertaining and informative. So thanks, and see you again next year!
Shelly Altman, California, USA (Philippines 2017)


It was a terrific trip, Lee! Magical snorkeling and the boat, crew and our fellow travellers made for a wonderful adventure. Fish nerd heaven! Thanks again for all you put into it.
Cara Bowers, New York, USA (Philippines 2017)


This trip was beyond all expectations!  I learned just how little I know about life in the ocean and can’t wait to learn more.  Ethan and Lee are wonderful teachers and the boat crew was unbeatable as were the accommodations!
Jackie Bell, California, USA (Komodo 2016)


Absolute Nirvana: Raja Ampat – the most spectacular marine biodiversity in the world combined with the incredible expertise of CTA. I’ve lived in Palau and snorkeled all over the world, but no other experience came close to snorkeling Raja Ampat with Lee, Ethan, and Dave. Not only are they marine biologists and outstanding underwater photographers, they are experts on the pristine, isolated waters of Raja Ampat and how best to experience them. Their extensive knowledge of the fish and coral species, their habitats, and the tides and currents; attention to detail; and, emphasis on maximizing time in the water ensured a truly amazing snorkeling vacation. I’m looking forward to snorkeling Komodo with them in the future.
Susanne Lee, Maryland, USA (Raja Ampat, 2016)


What a wonderful experience Raja Ampat was: Thank you for showing us around that magical kingdom
Katherine Mosby, New York (Raja Ampat, 2016)


I had never done an organized snorkel tour before so I was pleasantly surprised when I went on my first one with CTA to Fiji and learned that everyone else on the tour had traveled with Lee & Ethan numerous times in the past to many exotic destinations. Having spent a fascinating 11 days with Lee & Ethan I now understand why they have such a loyal clientele: As marine biologists with years of experience snorkeling, doing underwater photography and leading tours, they are the ideal guides. They are very professional but are also a lot of fun and, in addition to leading fascinating snorkel tours each day, they are happy to share their knowledge and expertise with daily educational presentations on everything from local marine life and culture to coral reef biology and marine ecology. I am already planning my next CTA adventure!
Cindy Glancy, Princeville, Hawaii (Fiji, 2016)


We traveled with Lee on the Kimbe Bay, Papua New Guinea snorkeling exploratory and were not disappointed!  Each reef was exciting and very diverse in its own way.  We especially enjoyed Restorf Island and huge schools of many different fish on the exposed reefs.  This was a very satisfying and delightful snorkeling adventure on amazingly pristine reefs.
Kurt and Lianne Raynor, British Columbia, Canada (Papua New Guinea 2016)


Jan and I have agreed that this was one of our best trips ever thanks to Lee and Ethan as well as the crew and guests.
Paul and Jan Brown, Michigan, USA (Raja Ampat 2016)


Thank You! That was the Very Best Snorkeling Trip We’ve Ever Had!
-David and Audrey Northrop, New Mexico, USA (Raja Ampat, 2015)


The best snorkeling adventure ever! Raja Ampat has so much diversity that it is overwhelming…from the tiny nudibranchs and pigmy cuttlefish to the wobbegong shark and of course the magnificent manta rays. A wonderful trip enhanced by Lee’s and Ethan’s knowledge and enthusiasm. The evening lectures were great and not to be missed. Thank you both.
-Cindy Turkle and Dan Clark, Iowa, USA (Raja Ampat, 2015)


We wanted to thank you both again for making the trip to Raja Ampat such a fantastic experience. From the smallest nudibranch to the largest wobbegong shark we’ve every seen and all the ornate ghost pipefish, reef sharks, manta swirls, and teeming clouds of colorful fish in between, your good cheer, knowledge, and experience made this the trip of a lifetime!
-Janey Kaster, California, USA (Raja Ampat, 2015)


Ethan and Lee are the best in the business, and any trip they lead is bound to be fabulous. My recent trip to Raja was no exception – gorgeous corals, an incredible variety of fish, nudibranches, octopus, mantas, and many other creatures. All very well-organized, and enhanced by Ethan’s and Lee’s knowledge and skill. Thanks for a great trip!
-Cory Streisinger, Oregon, USA (Raja Ampat, 2015)


Incredible seascapes – hard corals, soft corals, sponges, fans, feather stars, anemones, nudibranchs, fish – pink, red, purple, yellow, orange, blue, green! And then, three species of sea turtles, dolphins, manta rays, frigate birds, sea eagle, kites, and hornbills! Thank you Lee and Ethan for a marvelous adventure!
-Beth Caldwell and Ken Greenwood, Georgia, USA (Raja Ampat 2015)


For the avid snorkeler, Coral Triangle Adventures is a seamless way to visit unique destinations. Lee and Ethan have taken care of the all the details, all we had to do was jump in to the water. They made sure that every day we saw something new and exciting. Every snorkel provides unique opportunities whether it was coral, fish, or a combination of both.
-John and Carol Fravel, California, USA (Komodo National Park 2015)


Thank you for a great trip to Komodo Island National Park! The coral reef diversity was breathtaking. The wealth of knowledge that you both bring to these trips is the main selling point for us. Our room on board was comfortable and spacious and we were pampered with delicious meals and snacks.  Having sweet ginger tea waiting after the morning snorkel and hot cocoa after the afternoon snorkel were wonderful treats. We look forward to going with you to Raja Ampat!
-Jo-Ann and Oren Leong, Hawaii, USA (Komodo National Park, 2015)


“We’ve snorkeled from Bonaire to the Great Barrier Reef and the Coral Triangle Adventures trip to Raja Ampat we did was the best organized and most beautiful snorkeling we have experienced.”
-Peter and Linda Beuret, California, USA (The Spice Islands, 2015)


“The trip to the Spice Islands with Lee and Ethan was the best snorkeling trip I’ve ever had the pleasure of taking, and I’ve been to some fantastic places. Beautiful coral gardens, lots of fish, and knowledgeable guides who are fun to be with make this a must-do trip for anyone who loves our coral reefs.”
-Kevin Kaster, California, USA (The Spice Island, 2015)


“Alor featured a nice variety of snorkeling habitats with some unusual creatures that one doesn’t often see, and we frequently stayed in the water for a good three hours. The land excursion to visit the Kalabahi market and to see the hillside tribal dances was a bonus. Lee and Ethan’s expertise made the trip all the more worthwhile!”
-Vicki Gutgesell, California, USA (Alor, Indonesia, 2014)


“We could stay in the water as long as we wanted when snorkeling, and that was extremely important since there was SO MUCH to see on these reefs.”     
-Rowena Sim, South Carolina, USA (Alor, Indonesia, 2014)


“Snorkeling in Alor, Indonesia, was wonderful! Beautiful reefs and incredible marine biodiversity. Everything was more special because the trip was very well organized and our guides, Ethan and Lee, were very professional, well experienced, prepared, and a lot of fun too! I can’t wait to go on another adventure with them…”     
-Sandra Criteli, New New, USA (Alor, Indonesia, 2014)
