Amazing Underground River
After a scenic 45-minute ferry ride to Playa del Carmen from Cozumel, you will board your ground transportation to this awe-inspiring cave system. Be entertained along the way with fun and educational facts from your guide who will explain the specific and very interesting facts of the amazing natural wonder you are about to see.
Once in the heart of the jungle, you won't believe your eyes when you arrive to admire the incredible structures that took around 65 million years to form. This ancient, underwater cave system tour is perfect for adrenaline junkies and those who love nature.
First on your Cozumel excursion, discover these amazing caves on a walking exploration while learning all about the stalagmites and stalactites that have formed over a vast period of time. Then, jump into the fresh crystalline water and swim through the chambers connected by long, incredibly beautiful, low ceiling caves.
This is a true work of art courtesy of Mother Nature and was considered by the ancient Mayan civilization as a sacred place used by priests and warriors for important rituals.
After this unforgettable excursion in Cozumel, you will return to your transportation where you will enjoy a delicious light snack while traveling back to Playa del Carmen, where you will catch the ferry for the return ride to Cozumel.

We recently did the secret river tour while on a seven day cruise. This was our favourite excursion, not only was it a nice small group of only 9 people, but the guide was incredibly knowledgeable and friendly. The location was gorgeous, what a great day we had! If you are looking for an adventure than this is the spot for you. Mix together a little science, beautiful surroundings and Stephen our Italian guide and you have perfection!

This was THE best tour of our cruise, (and we took four.) The guide was enthusiastic and knowledgeable, the site was magnificent and only four of us were on the trip with him. This is not for anyone who is claustrophobic or has a bad back or knees. You wear a wetsuit. The connections were very well organized. We have found Costco tours superior in every way to other cruise tours.

My husband, two sons (12 & 15) and I had an amazing time on this tour! Our guide, Francesca, was the best! She told us all about the caves and formations, and really made the whole experience even more special. It was nice because our group was relatively small (12 people). I highly recommend this tour!

I couldn't have imagined how beautiful it was underneath the ground. It was a little scary at first and the water was cold but the fear was overcome by fascination. The tour guide was very knowledgeable.

As a group of 5 we booked this tour. We have taken many cruises and visited the same ports we were looking for something different to do. We read a few reviews off the internet and were not 100% sure. Some talked about water temperatures, tight spaces and high pressure picture sales. We experienced none of that! We were given wet suits, helmets with a lamp and water shoes (these are cleaned after each use as we had to leave them inside out after wearing to facilitate this process). The temperature did not seem cold (and I prefer my water to feel like bath water). Never did we do anything more than crouch. Our guide was knowledge able and passionate about the underground caves. Our group consisted of 11 people and the other group that travelled from the port with us had 12 with a different guide. We would highly recommend this experience. We were allowed use our own cameras and finished our trek with a swim in an underground natural pool. An excursion not to miss!
