A Guide to the Rio Secreto Caves
👉 Jump to: What is Rio Secreto? | Tours Review | How to Visit | Alternatives
The Rio Secreto Nature Reserve was easily one of the coolest things I did during the three months I spent in Playa del Carmen, Mexico.
Rio Secreto is a magical private complex of underground caves that’s been turned into an ecological park. Inside, you’ll find five cave complexes filled with thousands of stunning stalactites and a refreshing underground river.
In this guide, I’ll explain everything you need to know to visit yourself.

What is Rio Secreto?
Rio Secreto is an underground natural reserve located on Mexico’s Riviera Maya near Playa del Carmen. Rio Secreto consists of five caverns that form part of an enormous underground cave network. The name Rio Secreto in Spanish means “secret river.”

I have to admit that before actually visiting Rio Secreto, I was a bit confused about what it even is. It’s located on the highway right next to Xcaret and Xplor, which made me assume it was sort of an adventure theme park like those sites.
Well, I was wrong.
The Rio Secreto caves are filled with some truly dramatic mineral formations and play host to a surprisingly variety of wildlife. While, in disclosure, my ticket was provided complimentary by the park, I would happily have paid the cost of admission to enjoy this awesome and unique experience.
Visiting the park is a great family activity for those with kids looking for a day trip from Playa del Carmen, Tulum, or Cancun. But even if you don’t have kids with you, you might feel like one exploring this underground river.
My Experience Taking a Rio Secreto Tour

You can only go through the organized tours offered by reserve. The tours will take you hiking and swimming through about a one kilometer stretch of one of the caves (meaning your visit will represent only a tiny taste of this vast reserve).
All tours of Rio Secreto start at the park’s entrance just off the highway. You’ll watch a brief video while you wait for your group to arrive and sign a liability waiver. Then you and your new friends will pile into a van for the seven kilometer ride deep into the jungle where the caverns lie.
Once there, you’ll meet your tour guide and receive a brief orientation to the Rio Secreto park.
There are free lockers where you can change and leave your stuff (you need nothing but your swimsuit). You’ll be provided with special water shoes, a mandatory life jacket, and a helmet with a lamp.

Wet suits are available as well but are optional (I wore one, but in retrospect didn’t feel that it was necessary). You’ll also be required to shower off to prevent the introduction of foreign substances into the reserve’s delicate water.
After that, your guide will take you to witness a brief traditional Mayan ceremony before descending into the cave.
The actual tour of the cave itself only lasts about one hour, but it’s an hour that you won’t soon forget.
The tours are only done with small groups of 10 of so, and you don’t see other groups during your tour, which means that you really get to feel connected to the caves.
Your guide will tell you about the history of the cave, explain how the magical minerals formed, and will point out wildlife along the way (there are two types of fish in the river, as well as many insects, bats, and other animals).
About half of the time you’ll be walking through dry cave bedrock and the rest of the time you’ll either be wading or swimming through the underground river. The water is a cool and refreshing temperature, but you get used to it easily!
My favorite part of the tour, though?
At one point the guide made us all turn off our headlamps and sit in pitch black silence for a few minutes to just soak in the spooky sounds of the cave. It makes for quite the sensory experience!
After the tour completes, you’ll have a chance to shower and change up and then enjoy an included buffet before taking the van back to the entrance.

How to Visit Rio Secreto

If you’re planning your own trip to Rio Secreto, here’s a few things you should know before you go:
How to Get to to the Park
Río Secreto lies just a few miles south of Playa del Carmen (Google Maps). Here is a map:
The reserve offers transportation-inclusive packages that will pick you up and drop you off in your hotel anywhere in the Riviera Maya for about $119 per adult and $59.50 per child. That’s about $30 more than the cost of a basic ticket without transportation ($89 per person).
You can also easily organize your own transport to the reserve. Any taxi driver will know its location. A one-way taxi ride from Playa del Carmen should be about 190-200 pesos (~$10 USD). Expect that taxis from Tulum or Cancun will be considerably more expensive though, perhaps over $100 USD.
You can also take the collectivos (public minibuses) if coming from Cancun or Tulum, which will cost only a couple dollars per person at most. Just be sure to tell the driver your drop off spot clearly when you get on.
What To Bring
The only thing you need for your tour is your swimsuit and maybe a towel to dry up. Everything else will be provided to you. You don’t even need to bother with sunscreen or insect repellent, since there’s no sun and you’d have to wash those off anyway.
And you don’t need to bother with a camera either, since there isn’t enough light inside the caves to take photos (don’t worry: each group is accompanying by a photographer and you can purchase their pictures afterwards).

Other Helpful Tips
Here’s a few other random assorted tips to make the most out of your visit:
- 🚻 Be sure to use the restroom before entering the caves, as there is nowhere to go inside and the guides are VERY serious about not polluting the underground with your bodily waste.
- 🩳 While you have the option of wearing a wetsuit, I did and in retrospect would advise to give it a pass. I found it a bit hot and musty and honestly the water wasn’t cold enough to require one.
- 📷 You can’t take a camera in with you, but there is a photographer that will take lots of awesome pictures of your group and then make them available for sale to you on a USB after the tour.

Is it fine to go through the tour barefoot or do you recommend water shoes?
Hi Stephanie,
If I remember correctly, I do think wearing water shoes is required. I know you can bring your own, but I am not 100% sure about if they are required. I would recommend contacting Rio Secreto and asking if it is important to you.
I hope you enjoy your visit to Mexico!

Hi, is it imperative to book the tour in advance?
If you don’t need hotel pickup, no. But tours are timed, so you might want to book at least the day before to lock in your time.
is there lots of hills and rocks to climb up over during the hikes? Is it sliperry?
Outside of the cave network, it’s all flat and you’re transported in vehicles anyway. Inside the cave network, you do have to wait through water and climb through a few small boulders. So, in places, it could be slippery. But the guides are pretty good at helping, and you can also go with life jackets. I would say a low to moderate level of fitness is required.
Thanks this is a very informative post.
We will be there with our 3 year old. I read somewhere that there is baby sitting service available for this tour. Have you had a chance to spot that? Was it good?
Thanks
That’s a good question. I would suggest calling Rio Secreto at 1-888-257-6087. If you find out, let us all know please!
Hi there, very useful information. We are going to Playa Del Carmen next month from Canada and really interested in this tour. But I have few questionsL
1. I am thinking about just booking a base admission ticket, what is the difference between base and plus?
2. I can’t swim at all, is it a problem?
3. Also my child is only 11 year old, is the tour too challenging for the preteen?
Rio Secreto gives you life jackets to wear, so depending on your comfort level it would probably be ok. They allow children and I think an 11 year old could definitely do it. I’d suggest confirming with them on both of those points. The Plus ticket includes a light show at the Salon de la Paz.
Can I bring my phone in a waterproof pouch and tuck it inside my wetsuit? I’m uncomfortable leaving valuables in a locker.
I am not sure if that will be permitted. I will say that I’d be more worried about dropping it in the cave or it coming out while swimming. Rio Secreto is a professional operation and the lockers should be attended to at all times.
No, I was there yesterday and you are not allowed to take anything with you apart from walking stick. The only thing is that photos taken by their photographer are 25USD each or 99 USD for all of them. Not cheap considering that they only send you a link to download them
Hope this helps.
Is the hike difficult? Or it’s just a simple walk? Is there any crawling required? Will an obese person fit into those caves?
The walk is very very easy. The caves are mostly very large and so for the most part I think you should be fine. Just talk to your guide if you have concerns, as there are different routes through different caves. I hope you enjoy Rio Secreto!
