Mexico’s Rivera Maya is known for its incredible beaches, lush jungles, and all-inclusive resorts. Not many travelers know that this region is also home to many protected areas where you can find untouched landscapes and see many animals in their prime habitat. 

One of them is Sian Ka’an, a biosphere reserve that is home to an array of biodiversity such as manatees, dolphins, turtles, and rays. Translated as “Entrance to the Sky” from the Mayan language, Sian Ka’an is one of the most popular day trips from Tulum.

In this article, I’m going to give you all the details on how to visit Sian Ka’an, one of the hidden gems of Mexico’s Caribbean. 

Why visit Sian Ka’an Biosphere Reserve?

Sian Ka’an is one of the best places to visit in Yucatan if you are looking to get off the beaten track and spend time in nature. 

Sian Kaan is a designated UNESCO World Heritage Site that covers 528,000 hectares and is the second-largest biosphere in Mexico. It is one of the biggest protected habitats in Mexico’s Rivera Maya. 

The biosphere is home to more than 300 species of birds, 400 types of fish, 100 mammals, and 40 amphibians. When you visit Sian Ka’an on a tour, you will likely see some animals in the wild.

Sian Ka’an has several types of tropical forests, one of the most pristine wetlands in the region, lagoons, extensive mangrove stands, as well as sandy beaches, and dunes. It also protects part of the Mesoamerican Barrier Reef, the second largest barrier reef in the world.

I visited Sian Ka’an numerous times and have seen manatees, dolphins, and manta rays on different trips all within a close distance from the boat. 🤩

All animals within Sian Ka’an Biosphere Reserve are protected which means you can’s get close to them further than a specified distance. Seeing these animals is NOT a guarantee on your tour, you can just hope that your boat will pass the spot where you can get a look at dolphins or manatees.

Visiting Sian Ka’an is one of the best things to do in Mexico, and I highly recommend you include it in your Yucatan itinerary!

4. Sian Ka’an tours from Muyil 

Another option is to book Sian Ka’an tours from Muyil, an ancient Mayan ruin site about 20 minutes south of Tulum. Muyil sits along Highway 307 between Tulum and Bacalar, and until recently was mostly overlooked by tourists. 

Although Muyil is a small archeological area, it’s still one of the best Mayan ruins in Mexico. Muyil was one of the earliest and longest inhabited Mayan sites, thanks to its strategic location, and it boasts an impressive collection of Mayan ruins including the El Castillo pyramid.

From Muyil you will proceed along the trail that meanders through a beautiful cenote before you arrive at a tall observation tower. Climb to the top of the tower as it provides an incredible overview of the wetlands and the surrounding lagoon of the Sian Ka’an.

After climbing the tower, go back to the trail and proceed going straight until you get to the little pier. That’s where Sian Ka’an tours depart from.

Muyil is about 24 kilometers south of Tulum. You can get here by colectivo or car, and leave you vehicle in a parking lot near the entrance.

Some offers include both a guided tour of Muyil ruins and Sian Kaan, while other tours include only Sian Kaan

5. Sian Ka’an tours from Playa Del Carmen

Visiting Sian Ka’an from Playa Del Carmen is not one of the most popular options, simply because it’s much further than Tulum. Still, if you are spending your vacation in Playa Del Carmen, you can book one of guided Sian Ka’an tours that will pick you up and transport you back to your hotel.

How far is Sian Ka’an from Playa Del Carmen?

Sian Ka’an is roughly 100 kilometers away from Playa Del Carmen. It’s an amazing day trip, if you want to escape a busy destination for a day.

Driving from Tulum to Punta Allen

Punta Allen is a small fishing village within Sian Ka’an where you can buy Sian Ka’an tours from local guides, eat delicious food and spend the night gazing at the clear dark skies.

Punta Allen used to rely on fishing as its main source of income, now it’s very engaged in sustainability efforts and educating tourists about the importance of Sian Ka’an.

Punta Allen has some amenities, but overall, it’s a little developed area with a relaxed atmosphere and a tropical vibe that is perfect if you want to unplug and take a break from Tulum.

The road takes you through Sian Ka’an along the Caribbean coast until you reach Punta Allen. Keep in mind that during the rainy season this road can be very hard to drive, as it can get completely washed out. If you are visiting during the rainy season, booking one of the guided Sian Ka’an tours is a much better idea.
