I had trouble finding information about the reserve before visiting, so I will share what I have learned. There are only a few access points into the reserve: 1. Your first option is to take a guided tour with a provider. We did not do this, so I cannot speak to this, but presumably there are a number of tour providers who have boats and can take you to the remote areas that are impossible to access by car, such as the reefs off of the coast and the lagoons in the interior of the park. 2. If traveling by car or colectivo and not going with a tour, one access point is the Muyil Archaeological Zone. There is a nature boardwalk (called the Canan Ha trail) that goes from the ruins to the Laguna de Muyil, where there is a boat dock. From the dock you can take a boat tour of the lagoon and float down the Mayan canal that once connected Muyil to the ocean. You can schedule this boat tour at the Muyil ticket counter. 3. The other access point is to take Hwy 15 south from Tulum towards Punta Allen. This will take you into the reserve. However, this road is exceptionally bad starting in Tulum, covered in potholes and deep puddles. It is very difficult to drive down and you may damage your car.

We went there with a tour organized by the local community. The staff was super friendly and open to share thoughts. On our boat trip we stopped on a beach that was full of littering. When talking with the tour guides they said that the place was completely abandoned by the administration. Even though they do their best to preserve it, it is only that much they can do. I hope everyone who visits this place reports it to put some pressure on the admin. 🙏🏽

You can skip it! 100 pesos entrance fee for a bad road which is mainly closed on both sites. Everything is private and the beaches plus the nature is full of plastic. I think mexicos beautiful nature is close to be past thing. Its sad but when you see what you can buy here in the supermarkets its not a surprise. Plus most of the people here just only think on profit and don't care about their nature.

This place is only for extremely patient people, that's for sure. To get there you need to either drive or go on a tour, but either way the trip is very long due to the fact that the road is not paved and it's EXTREMELY bumpy. So the driver is forced to go super slowly while the vehicle is shaking for 3 hours on the way there and 3 on the way back (from playa del carmen , a little les from tulum). It's worth doing it at least once though, because the lagoon is spectacular. You can see dolphins, turtles and manatees with their babies, in their natural habitat!

The natural reserve is hard to see if you don't take the overpriced boat tours. The price has rised probably due to the lack of competition. We decided to take the road that runs along the lagoon and go to Punta Allen. The road is in good shape the first few kilometers after it's bumpy. But almost all the shore side is private. We didn't get how it's possible since it's a natural reserve supposed to be preserved (that's they tell you everytime you pay the entry). Thankfully, there was a bridge where we could see crocodiles and have a view on the lagoon. But the worst part was when we finally could reach the beach. It was full of littering. And it's all like this all along the natural reserve. They should do something quick. All the littering must come from Tulum by the sea. It's urgent to take care of this!

If you have money take the full option of trip. I took the less expensive and probably didn't see a lot of beuatiful reserve. We had about 2 hour trip from Tulum and the road was awful. A lot of holes in the road. But reserve is beuatiful. We had also a trip with a boat. Unfortunatelly we haven't seen dolphins or crocodiles but we saw turtle. There was also snorkeling. The reef isn't breathtaking but fish are colorful and nice. The most amazing is natural pool, you can take beautiful pictures there. To sum up it is worth seeing but it's not as much amazing as people from travel agency saying while they trying to persuade you to take this trip.

Really sad to be giving this one star. The road here is absolutely ridiculous. Really. This is not hyperbole. You'll be lucky to get back with your car intact. But even if you do, it's 4 intensely nervous hours of driving through potholes that you will never get back. Even with a jeep it's just not worth it. And that's 4 hours just to get nowhere and back. Seriously, just say no. Plenty of other places to explore.

Clearly none of the entrance fee (105 peso pp) is going towards repairing facilities/roads or litter picking. Complete waste of time; you likely won’t see any wildlife other than birds, the road is in dire need or repair, litter is EVERYWHERE - the beach is disgusting with litter all over the place (that’s where there’s public access - many areas are private). Expected more for a protected area. Also no fuel anywhere once you’re out of Tulum so take extra or watch the gage. Better to spend your time in a national park where money is spent actually conserving it, rather than leaving fishing nets and broken beer bottles strewn all over the beach.

Turtles, crabs, dolphins, crocodiles and Coral reef. Bird Islands (mangrove Islands) and lots of beautiful scenery. I fully recommend visiting.

I went on my bike, so worthy it, find a beach just for me

This is by far mine and my wife's favourite trip we have done in mexico so far and we are on around 10 now, amazing day out, learn so much about the wildlife and what a place to see them all in there own habitat, will be doing again when we return, can't wait

Amazing place, simply amazing. Brilliant management plan for tourism, fingers crossed that doesn't change. Pepe was an awesome guide, very knowledgeable and had an addictive level of enthusiasm. Would love to return in 20 years to see any changes

Beautiful scenery. Great boardwalk through the jungle, amazing view from the watch tower, and boat ride with the canal float with our own captain. You don’t need to go on a tour to do this. Best way is by Colectivo, pay the entry/boat fees, and you’re sorted. Go early to avoid tour groups.

The beaches and the jungle along the road is littered with garbage. They are heaving construction equipment haul a lot of material for building a new hotelzone on the way but are not willing to fix the road to the village at the peninsulas end. The nature is rather disappointing too. Lots of the coral reefs are dead and there is little fish. We spotted some giant turtles and "hunted" them down so that we the tourist could see some seconds in which these impressive animals went up for getting air - but you could see that they desperately tried to get away from us and were quite stressed. Getting there takes ages. Not worth it at all.

Beautiful quiet area. The road is bad but it’s also do able with experience. Look for the alligator under the bridge. The really sad part is that there is an extreme amount of trash along the otherwise stunning beach side of the peninsula. Really an insane, upsetting amount. Don’t be fooled by all the greenwashing in Tulum, be a good human and do your absolute best to minimize the waste you generate while on vacation.

It is definitely the best place I’ve visited in Mexico so far. As a huge animal lover, it was an emotional and exciting experience. I highly recommend visiting Sian Ka’an.

Just let the nature be nature. Dont pay the overpriced prices there. Dont go there and support the people who are supposed to take care of the park - they threw their beer bottles into the lagoon just in front of us. If you care about nature, stay far far away from there, even if it would be beautiful.

Great nature reserve. We spotted dolphins, manatees, turtles and many other animals. The road from Tulum to Punta Allen is very very bad. A lot of (big) holes and bumps. Driving here is very slow and bumpy. Once you're on a boat it's absolutely great. Definitely worth a visit.

My husband and I came to celebrate our anniversary and had such a great time so far! All around the service here was great. Specifically, we loved Alexander from the entertainment team! He did a great job of always making sure my husband and I knew what activities we could do! We love being active and Alexander made sure to keep us in the know.

We decided last minute to check this place out after reading various reviews we headed out. Upon getting there there were warnings from locals and general public that the roads were terrible. This was not the case. We drove a VW Gol and had zero problems. This is a perfect place to take grandma for a lazy Sunday afternoon ride. The birds were chirping, and a warm sun made for a perfect midday getaway. If I could give 6 stars I would.

We love visiting the Sian Ka'an and have returned multiple times. Luis, Mirian and Daniel in the buffet restaurants take very good care of you and are attentive. Victor on the animation team leads very goof aqua gym sessions, paying attention to any injuries and giving advice rather than pushing you. Love this hotel!

Floating down the canals was my favorite part of my visit to Tulum - such a great time! So much natural beauty and history here. There are Mayan Ruins in the jungle - the hike to see them is easy. Only unpleasant bit were the mosquitoes and bathrooms facilities.

A wonderful park which definitely deserves a visit. Make sure you get a good tour that takes you snorkelling to the reef

Give yourself a minimum of a day to explore. You could honestly spend a week just in the reserve and still have more to see. If you're taking the drive down the peninsula just prepare yourself for that to be a whole day as well as it's a dirt road. It's beautiful and there is so much biodiversity to enjoy! Definitely worth the experience!
