Sway, Shanti, and Anthony were literally the best tour guides! Had so much fun and they made sure that everyone was learning, joking, and safe! Would recommend 100% and will come back in the future!

Amazing experience exploring the mangroves and the land and sea in the lagoon. TONS of wildlife and lots of great information about everything that we encountered. Great water and lunch as well. Our guide was amazing and tailored the teaching to each of our kids and both my wife and I (adults and a 9, 7, and 4 year old). All came away very happy and informed. Ended up being a private tour! Highly recommend!

Great tour! Our guide was very knowledgeable. Took his time. Didn’t rush anyone. The lunch was delicious as well; chicken wrap. This is our second time with this company and would go again.
