Floating Through Paradise: An Afternoon at Los Rapidos Bacalar

If you’ve ever dreamed of floating effortlessly through a crystal-clear river, surrounded by vibrant nature and ancient secrets, Los Rapidos Bacalar is the place to do it. It’s one of those spots that makes you slow down, breathe deeply, and wonder why you don’t do this kind of thing more often. At least that how it made me feel.

What Makes Los Rápidos So Special?

Tucked away about 20 minutes south of Bacalar’s town center, Los Rapidos is a narrow stretch of water where the lagoon’s famous seven shades of blue meet a soft, steady current. The name, which translate to “The Rapids”, might sound a little intimidating, but in reality, it’s more like a natural lazy river. The water moves just fast enough to carry you gently downstream without any effort.

Unlike the main part of Bacalar Lagoon, where the water sits still like a massive, glassy mirror, this section flows between two banks lined with mangroves and some of the oldest living organisms on the planet—stromatolites. Keep reading to learn more….

Getting There—A Short Trip Into Nature

Los Rápidos is about 13 kilometers from the heart of Bacalar. If you have a rental car, it’s an easy drive down Highway 307, with a small turnoff leading to the entrance. Just type “los rapidos bacalar” into your Google Maps and you will be directed straight there.

If you’re feeling adventurous, you can hop in a colectivo heading toward Chetumal, but be prepared for a hot walk from the highway to the lagoon. Taxis from town typically charge around 200 pesos each way. We did not see any taxis waiting in the parking lot when we left so be sure to arrange pick up with the cab driver who dropped you off or you may be trekking it back to the highway to flag down a ride!

As you arrive, you’ll see a wooden walkway leading over the water, with thatched-roof palapas and a casual restaurant perched along the edge of the river. When you arrive, there are plenty of signs with information about the area and some of its unique characteristics. A greeter will meet you at the entrance to explain the costs, the rules and restrictions particular to this special place. Our greeter spoke English, Spanish and French!

What It Costs & What You Get

The entrance fee is 200 pesos per person (around $10 USD), and 150 pesos for children ages 2-10. There is a also a discount for senior citizens. You will be given a bracelet which gives you parking, access to the entire area for the day including the use of the changing stalls and restrooms. There are lockers for rent (50 pesos rental plus 50 pesos deposit) which are essential for keeping your valuables safe while you are enjoying the water. One locker was all we needed for the two of us.

Life jackets are also included (which you’ll definitely want if you’re not a strong swimmer) but not mandatory for the float or swimming areas. There are kayaks for rent as well, both single and tandem, if you want to explore beyond the main swimming area. Life jackets are required if you are using the kayaks.

A Natural Water Park Without the Chaos

The first thing you’ll want to do? Jump in of course!

Once you arrive and get your items secured, start walking to the right, upstream along the wooden walkway. There are several entry points along the way, but we went all the way to the end. Here, you will find steps that carry you down into the water.

The water is cool but not cold, and the current catches you immediately, pulling you effortlessly along. Within seconds, you’re gliding past tangled roots, patches of vibrant green plants swaying beneath the surface, and those otherworldly stromatolites—ancient rock-like formations that are actually living microorganisms.

Floating here feels like pressing pause on life. There are no motor crafts, no noisy tour groups—just the sound of water, the occasional call of a bird, soft giggles from your fellow floaters and the feeling of the sun warming your skin.

If you’re traveling with kids, they’ll love this. The current is gentle enough for little ones (with life jackets, of course), and older kids can spend hours floating, swimming, snorkeling and exploring the wooden boardwalk. Even if you’re not a strong swimmer, I think you can still enjoy this experience using a life jacket.

Lunch with a View

After a couple of rounds floating the river, hunger starts to kick in. It was Sunday when we visited and I had my heart set on finding some barbacoa on the way home so we passed on lunch. But between floats, we settled in to the wooden chairs and tables set up at the waters edge and had a few cold beers, an Indio for Jim (60 pesos) and a for me, a “Marea Roja” (120 pesos). That’s their spin on an “Ojo Rojo” and it sure hit the spot.

If you are keen to eat, the on-site restaurant has you covered. It’s nothing fancy—just simple, fresh dishes like ceviches, aguachiles, grilled fish, and nachos served to the tables under the big palapa or overlooking the water under the coconut palms. Given the gorgeous location, I felt like the prices were very fair.

Be warned: I’ve heard at peak times, some of the seating areas closer to the water require a minimum spend. If you’re not planning on eating much, ask a server where to sit or grab a table further back. There were plenty of tables and chairs when we were there and the servers seemed unbothered that we were just having a few cervezas. Your mileage may vary.

The Stromatolites—Ancient Life in a Living Lagoon

Los Rápidos isn’t just a beautiful place to float and relax—it’s also home to one of the rarest and most fragile ecosystems on the planet. The stromatolites, those dark, rounded formations beneath the water’s surface, aren’t just slippery rocks. They are living organisms, formed by colonies of cyanobacteria that have been around for over 3.5 billion years. These tiny creatures helped shape the Earth’s atmosphere, producing the oxygen that made life as we know it possible.

In Bacalar, stromatolites act as natural water filters, playing a crucial role in keeping the lagoon’s water clear and healthy. They help balance the ecosystem, absorbing excess nutrients and preventing algae overgrowth. Without them, Bacalar’s famous seven shades of blue could disappear.

Protecting the Stromatolites: The Rules You Need to Follow

To protect these ancient life forms, Los Rápidos has strict rules in place, and it’s everyone’s responsibility to follow them:

• No stepping on the stromatolites – They may look like solid rocks, but they are delicate, and even a single step can damage them.
• No touching or sitting on them – The bacteria that form stromatolites grow slowly, and any disturbance can stop their development.
• No sunscreen, lotions, or insect repellent in the water – Even “reef-safe” sunscreen contains chemicals that can harm the microorganisms living on the stromatolites. It’s best to wear a rash guard for sun protection instead.
• No littering – The lagoon is a fragile ecosystem, and any plastic, food waste, or other trash can disrupt the natural balance.
• Stay within designated swimming areas – Floating through the current is encouraged, but some areas are off-limits to allow the stromatolites to thrive undisturbed.

Wildlife Encounters—Who Else Calls This Place Home?

Aside from the stromatolites, Los Rápidos is home to a variety of fish, turtles, and birds. Keep an eye out for small, silvery fish darting beneath you as you float, and if you’re lucky (like we were), you might spot a heron or kingfisher hunting in the tall grasses along the shore.

On quieter days, you may even see an iguana sunning itself on a branch or a curious turtle popping its head above the surface before disappearing again. The lagoon’s ecosystem is fragile but full of life, and Los Rápidos offers one of the best ways to experience it up close.

What to Bring (and What NOT to Bring) to Los Rapidos Bacalar

A trip to Los Rapidos Bacalar is all about relaxing, floating, and enjoying nature, but bringing the right gear can make your experience even better. Since this is a protected ecosystem, there are also a few things you should leave behind to help keep the lagoon pristine.

Essentials to Bring:

• Swimsuit – You’ll be in the water most of the time, so wear something comfortable for floating and swimming.
• Rash Guard or Long-Sleeve Swim Shirt – Since sunscreen isn’t allowed, the best way to protect your skin from the sun is with a lightweight, UV-protective shirt.
• Water Shoes – While the bottom is mostly soft sand, there are some rocky areas near the entrance and along the boardwalk. I didn’t bring mine and I didn’t really feel like I was missing them except on the gravel around the seating areas.
• Dry Bag – If you plan on bringing your phone, keys, or cash near the water, a dry bag will keep everything safe and dry. If you don’t want to rent a locker, this is the way to go.
• Towel – There are no towel rentals at Los Rápidos, so bring your own to dry off after floating.
• Cash (pesos) – The entrance fee, food, and drinks are cash-only, and there’s no ATM on-site. Bring enough pesos to cover entrance fees, locker rental, food, and transport back to Bacalar.
• Snorkel Mask or Goggles – The water is incredibly clear, and wearing a snorkel mask or goggles will let you see the fish and stromatolites up close.
• Sunglasses and a Hat – The sun is strong, and there is no shade in the water. A hat and sunglasses will help keep you comfortable in the water and out. I kept my baseball cap on in the water and I was glad to have it.
• GoPro or Waterproof Camera – Floating down the current is an experience you’ll want to remember, and an underwater camera will help you capture it.
• Change of Clothes – If you’re heading back to town afterward, a dry outfit will make your return more comfortable.

What NOT to Bring:

• Sunscreen, Lotions, or Bug Spray – Even reef-safe sunscreen damages the stromatolites and disrupts the lagoon’s fragile ecosystem. If you need sun protection, wear a rash guard instead.
• Speakers or Loud Music – The magic of Los Rápidos is its peaceful atmosphere. If you want music, bring headphones and keep it low.
• Food, Beverages or Alcohol from Outside – The on-site restaurant sells great food and drinks, and bringing your own alcohol isn’t allowed.
• Big Flotation Devices – Pool floats and large inflatables aren’t allowed since they disrupt the natural flow of the water and can harm the environment. Use the life jackets, which are provided with your entry fee.

Final Thoughts—Is Los Rapidos Worth It?

Absolutely. It’s the kind of place that feels untouched, where nature takes center stage, and the pace of life slows down. Whether you’re looking for a peaceful escape, a fun spot for the family, or just a chance to float through paradise, Los Rápidos delivers.

Just don’t rush it. Arrive early, take your time, and let the current carry you away—literally and figuratively. You won’t regret it. Check out the gallery below for more shots from our day!
