Lunch is included once you are back in the daylight. We pick you up and bring you back after you have changed. 🔑 Key Details Duration: About 4 hours, including hotel pickup where this route provides it Minimum age: 4 Group size: Up to 25 guests Pickup: Hotel pickup is part of this route Briefing: Guides cover safety and equipment before each active part 🗺️ What to Expect Check-in is followed by an introduction and a short ceremony at the entrance, before the wetsuits, so you get a feel for the place while you can still see it properly. Then the helmet light, the suit, and a talk on the footing before you enter the river cave. Inside you walk and swim through the chambers in a line, close enough to see the person ahead, which is oddly peaceful. The swims are short stretches between the walking, the guide names them while you can still see the group, and lunch is after you have changed, on the surface. 📍 Location Rio Secreto is an underground river inland from Playa del Carmen, so the beach town is the nearest coast and the day itself is below ground. The active part is water and rock, entrance at the reserve, daylight something you walk back out into. The chambers are dark aside from the helmet lights, and those lights are checked before you go in, while you can still see what you are switching on. The guide sets the pace, and you stay with them from the ceremony until you are out and ready to eat. ✅ Prerequisites You will need to be at least 4 years old. Bring swimwear for under the wetsuit and a change of clothes for after, because you will be wet, and a dry shirt at lunch feels like a luxury. You should be happy walking and swimming short stretches in a group, light on, person ahead in view. The guide explains where the swims are before the first pool, so it is not a surprise when the floor becomes water. ⭐ Why Choose Us The talk and the ceremony happen before you go under, and the wetsuit is fitted then too, because the river is cool and halfway through a chamber is a bad time to discover that. The first pool is described while you can still picture it. The group moves as one line, which is how you keep sight of the person ahead and why the cave feels calm instead of confusing. If the water is not right for a section, the staff hold it and tell you before you enter. Lunch waits on the surf… ### Essential information _None._ ### What’s included Guided activity segments described for this route Professional guides or instructors Safety equipment where the activity requires it Meals or drinks when listed in the included section Round trip transport when listed in the included section ### What’s not included Transport to the meeting point if you are outside the pickup zone Marine or park fees payable locally Gratuities and souvenirs Biodegradable sunscreen and personal items Optional photo packages ### Kit list Swimwear and towel when water is included Closed-toe shoes for adventure segments Biodegradable sunscreen and hat Cash for fees and gratuities Valid ID for children where required ## FAQs ### Is lunch or refreshments included? Lunch is included on this visit, so you do not need to bring a meal with you. If you have a dietary need, tell the guide at the start of the day so they can pass it on before you sit down. Bring water for the time you spend between stops, because those gaps can be longer than they look. Extra drinks may be for sale, but do not count on a shop being open at every place you stop. ### What if weather affects the route? Light rain does not usually stop the visit. Lightning, a rough sea or a track that is too soft can shorten or move a section, and the guide explains that before you continue. You will hear the change before you kit up for the next part. The group stays together while that decision is made. ### Can children take part? Anyone taking part needs to be at least 4 years old, and children need an adult with them. The guide will say before a section starts if it is not suitable for someone in your group. They need to be able to listen to the safety talk and stay with the group. The same briefing applies to adults and to children. ### Do I need to swim confidently? You should be comfortable wearing a life jacket and following the guide in the water. You do not need to be a strong swimmer. The guide stays nearby and calls the group out together. If you would like to stay closer to the entry, say so before you get in. ### Are photos or videos available? You can bring a phone or a camera if it is secure and you can spare a hand. Ask the crew before you attach anything to a helmet, a harness or a handlebar. If someone is taking photos for the group that day, the crew will say so when you arrive. They will also tell you where to collect them afterwards. ### What marine or park fees apply? If a ruin, a reserve or a beach asks for a local payment, the guide explains it before you get to the entrance. It helps to have a little cash with you in case that happens. Tips for the crew are your own choice at the end of the day. The guide is the person to ask if you are not sure what a site is asking for. ### Are lockers or changing rooms available? Bring a dry bag for a phone and anything else you want to keep dry. Ask the crew when you arrive if there is somewhere to change and leave a bag. Put your name on anything you set down. The group moves between stops, and bags are easy to mix up. ### Can I bring a camera or phone? A phone in a waterproof pouch is the simplest option on a boat or in the water. Ask the crew before you strap a camera to a helmet or a machine. Drones and flash are often not allowed near wildlife or at the ruins. Follow what the guide and the site ask on the day. ### What should I wear? Wear light clothes you can move in, closed shoes, and a hat. This includes a cave, so sun cream and a bottle of water are worth having from the start. Bring swimwear underneath if the visit includes a swim, and a dry layer for the van or the boat. Secure anything you do not want to lose. ### How strenuous is the activity? You should come ready for walking and short swims in an underground river. Most of the time is outside, so the heat is as much a part of the day as the activity itself. Take water when you need it, and tell the guide at the start if you want a slower place in the group. That is much easier than trying to catch them once everyone is already moving. ## Media - **Primary image URL (resolved in app; may be absolute)**: https://adventuro.com/cdn-cgi/image/width=1200,format=auto,quality=90/https://wp.adventuro.com/wp-content/uploads/2026/09/fa6c19bd-ecb4-4b6f-afb0-83b5bd5a47d5-4.jpeg - **Gallery image count**: 6 ## Limitations - Availability, exact session times, and final price may depend on the live booking flow. - This Markdown is generated from the same catalog fields as the public HTML page at the canonical URL above.
