TOUR DESCRIPTION

Río Secreto Salty & Sweet

Snorkel the World's Second Largest Coral Reef & Explore a Hidden Underground River

Experience two of the Riviera Maya's greatest natural wonders in one extraordinary adventure. From the vibrant colors of the Caribbean Sea to the mystical underground world of Río Secreto, this unforgettable journey combines marine exploration, breathtaking landscapes, and the ancient magic of the Mayan world.

Your adventure begins at the spectacular Puerto Morelos National Reef Park, home to a section of the Mesoamerican Barrier Reef, the second-largest coral reef system on Earth. Guided by experienced professionals, snorkel through crystal-clear turquoise waters where colorful coral gardens, tropical fish, rays, and an incredible diversity of marine life create one of the Caribbean's most spectacular underwater experiences.

After exploring the vibrant world beneath the sea, continue your journey into the heart of the jungle to discover the extraordinary Río Secreto Natural Reserve.

Hidden beneath the forests of Quintana Roo lies a breathtaking underground river where crystal-clear waters flow through magnificent caves filled with thousands of ancient stalactites and stalagmites. Accompanied by an expert guide, you'll walk and swim through this pristine subterranean world, surrounded by spectacular geological formations that have been sculpted over millions of years.

Considered one of Mexico's most remarkable natural treasures, Río Secreto offers much more than an adventure—it is a transformative experience that invites you to reconnect with nature while discovering the mystical landscapes once revered by the ancient Maya.

As a protected Natural Reserve, every visit follows strict sustainability practices, preserving this incredible ecosystem while allowing guests to experience its beauty responsibly.

After a day of unforgettable exploration, relax and enjoy a delicious buffet lunch with refreshing beverages before returning with memories that will last a lifetime.

On June 9th, my wife and I went on the Horseback riding excursion, and Oscar was once again our amazing guide. I have to tell everyone, he felt more like our cousin back home. He was very personable, and we were able to cut up with one another. He has a great sense of humor as well. He even helped us with our Spanish. When we arrived at the ranch, Eduardo “Lolo” was waiting for us. The horses were well fed and cared for, which made our hearts feel good because we knew they were cared for. We took a beautiful ride along the shoreline, talked, and laughed with Eduardo and Oscar. We were very thankful that Enrique was able to reschedule our excursion from the previous day because of the storm. OSCAR, we want to say, muchas gracias, mi amigo.

Amazing tour to Ixtapa Island! The staff was very friendly and attentive, and everything was perfectly organized. The beaches and crystal-clear water are a true paradise. We got to swim, snorkel, and enjoy every corner of the island. Definitely an experience that exceeded our expectations. We’ll be back for sure!

My name is Heidi and I live in Victoria, British Columbia (BC), Canada. Rate 5 star! January 2026 I went to Ixtapa for two weeks and stayed at Posada Real Hotel. Fernando was the Sunnyside representative in our hotel lobby. He was friendly, informative and spoke English very well. We did three excursions with Sunnyside. The tour to Ixtapa Island included a delicious hot lunch on the beach and I paid extra for a snorkelling guided tour. I was able to snorkel by myself after the introduction to the area and sea life. Our guide Mariella took great care to make sure we had the most enjoyable experience. The sunset cruise was so much fun, we celebrated my birthday that day. The crew of the catamaran Picante were amazing! They made sure that everyone was having a good time and provided entertainment that had everyone laughing. The food and drinks were good. The captain spoke English very well and told us about the sights along the way, we even saw humpback whales! The crew put out fishing rods and I reeled in a Spanish mackerel! (I am a fisherperson back home) The turtle release was a highlight for me as I have never done this before. We drove to a remote beach were a family works to conserve the turtle population. Our guide educated us on the endangered turtles and what they are doing to increase the population of green turtles specifically. It was an amazing feeling to dig up the baby turtles, hold them and then release then into the ocean surf. I highly recommend Sunnyside for excursions and will certainly book more with them the next time I am in Ixtapa. Thanks Fernando for making me feel special.

On June 5, 2026, my husband and I went on the City Tour, and Oscar was our guide. He was very knowledgeable about the areas around Zihuatanejo and Ixtapa. When we visited the La Ropa area, we stopped at the beach, where there were various restaurants and shops where you could make purchases. We stopped and saw various bird species, crocodiles, and iguanas. We grabbed a bite to eat at Chekos for lunch, and it was delicious, and the customer service was great. They were very friendly people. Afterward, we opted not to go to the downtown marketplace and instead went to the Parthenon. The view was breathtaking, and the artwork was beautiful. Even though the story behind the place sounds horrible, I am glad the government was able to turn it into something that could benefit its citizens. Thank you, Oscar, for making our excursion memorable, and thank you to Sunnyside for an amazing tour.
