What Travellers Say
Reviews Summary
Visitors rave about Cenote Sac Actun's breathtaking cave formations and crystal-clear waters, calling it one of the best cave experiences. The knowledgeable guides and unique geological features are frequently praised, making it an unforgettable adventure. However, some find the entry fee steep for the relatively short tour duration and note the bumpy road access.
"Best cave I have ever been to in my life. The water was crystal clear and cold perfect for a hot day in the jungle. The formations were amazing and were some of the prettiest I have ever seen. Despite the rough dirt road to enter the cave it is still worth it. Guide was very knowledgeable and did a good job talking about the cave and making sure we did not get lost in the giant cave. Highly recommend."

"This is a pretty cool semi-open cenote cave.
Pros:
You can swim in it
Get some great photos
Water is crystal clear so you can see the 3 types of fish (catfish, sardines & guppies)
Stalactites and Stalagmites are really neat
The Bats are big and active
Cons:
Tour was about 5 minutes
Noise travels really easily in the cave. We were fortunate to be there on a quiet day, but the one other group was super loud which was challenging in the space.
$650 entry fee. This includes your locker & lifejacket. Bring your own snorkel or goggles. You can spend the whole day at Casa Tortugas for $750 and they have 4 cenotes and full park access so you can spend a whole day there for better value for your dollar. That said, they do not have a cave like this one.
Over all its a good experience but you don't need a lot of time here to see it all. Once parked, an hour is more than enough for the cave swim. We did not pay for access to the remaining activities so I can't speak for the rest of it. *Note, give yourself extra time to drive the 3 km road in to the reception and then to the cenote itself as the roads do not allow for speed. Have fun!"

"One of the most beautiful cenote I have visited. We had a very fantastic guide who had a lot of expertise. We received wet suits and life jackets which were in a very good condition. We always felt very safe. Please bring your mosquito repellent."
