Quick answer: ATM Cave (Actun Tunichil Muknal) and Barton Creek Cave are both sacred Maya caves in Belize's Cayo District, but they make very different days. ATM is a hike, swim, and climb into a wet cave to see ancient Maya pottery and human skeletons up close. It is the more powerful experience, and it is physically demanding. Barton Creek is a calm canoe trip into a river cave, with pottery and bones visible on the ledges. It needs no hiking or swimming and works for almost any age.
Choose ATM if your group is active and wants a real adventure. Choose Barton Creek if you want to see a Maya cave in a relaxed way, or if anyone in your group is not comfortable hiking, swimming, or climbing.

For the ancient Maya, caves were entrances to Xibalba, the underworld. They came into caves like ATM and Barton Creek to hold ceremonies, leave offerings, and in some cases bury people. Both caves still hold what was left behind more than a thousand years ago. The big difference is how you reach it: at ATM you walk, swim, and climb to it, and at Barton Creek you paddle past it.
We are a local, private tour company based in Cayo, and our founder has been guiding in Belize since 1998. This guide is based on the trips we run and on the official rules from Belize's Institute of Archaeology (NICH).
ATM Cave: the full adventure
Actun Tunichil Muknal means "Cave of the Stone Sepulchre." It sits in the Tapir Mountain Nature Reserve, near Teakettle Village in Cayo. NICH lists the cave at about 3 miles long. The ancient Maya used it from around A.D. 300 to 600 for rituals to reach their gods and ancestors.
What the day is like
From San Ignacio, it is about 45 minutes by road, then about 45 minutes on foot through the forest, with several river crossings. At the entrance, you swim a short distance into the cave. Then you wade, scramble, and climb through the passages for several hours, sometimes squeezing between rocks with water up to your chest.
Near the end, you climb up into the dry main chamber, often called the Cathedral. You take off your shoes and walk in socks to protect the cave floor. Here, pottery and human remains lie where the Maya left them. The Belize Tourism Board counts 14 skeletons in the cave. The best known is the Crystal Maiden, the skeleton of a teenage girl covered in sparkling calcite. Look out for the Monkey Pot too, a carved vessel the Belize Tourism Board describes as one of only four found in Central America.
Key rules at ATM
- You must go with a licensed guide, and tickets must be booked in advance.
- NICH requires children to be at least 40 inches tall. Because of the swim and the climbing, we recommend ATM for confident kids of about 8 and older.
- Cameras and phones are not allowed inside, after an artifact was damaged in the past. Your guide stores them before you enter.
- The cave can close after heavy rain because the water rises. Guides check conditions every morning.
Is ATM Cave hard?
It is moderately hard. You do not need to be an athlete, but you should be comfortable walking for about 1.5 hours round trip, swimming a short distance, and climbing over wet rock in the dark. There are a few tight spots, so it can be difficult for anyone with a strong fear of enclosed spaces. If anyone in your group has mobility limits, heart or breathing problems, or cannot swim, talk to us before booking. Our full ATM Cave guide covers the rules and what to bring.
Barton Creek Cave: the gentle way to see a Maya cave
Barton Creek Cave is a protected archaeological reserve in Cayo, in the hills below the Mountain Pine Ridge. The only way in is by canoe, because Barton Creek flows right through the mountain.
Getting there
The drive is part of the adventure. The road from San Ignacio passes through the Mennonite farming community of Upper Barton Creek, and some parts are rough and bumpy. After heavy rain, the creek crossing on the road can close, so we check conditions before your tour.
What the tour is like
At the cave, you get a life jacket and a light, then paddle into a huge cave entrance. Your guide uses a strong spotlight to show you tall cave ceilings, crystal formations, and Maya pottery and bones resting on the ledges above the water. The Belize Tourism Board describes calcified skeletons and Maya ceramics in the cave, and many remains are still visible from the canoe. Tours usually go about a mile into the cave before turning around, depending on the water level.
There is no hiking or swimming. The canoe trip takes about 1 to 1.5 hours, and a half-day tour from San Ignacio is about 3.5 hours. Barton Creek pairs well with Xunantunich, the Mountain Pine Ridge, or a swim at a nearby waterfall.
Visitors must go with an authorized guide. NICH's published rules still include a swimming-ability requirement, even though you stay in the canoe, so tell us if anyone in your group cannot swim.
A sample day at each cave
| Time | ATM Cave | Barton Creek Cave |
|---|---|---|
| Early morning | Pickup and drive to the Tapir Mountain reserve | Pickup and drive through Upper Barton Creek |
| Morning | Jungle hike with river crossings, then the swim into the cave | Canoe trip into the cave, about 1 to 1.5 hours |
| Midday | Several hours inside the cave, then hike back | Back in San Ignacio, or continue to Xunantunich |
| Afternoon | Lunch, change into dry clothes, return | Free afternoon or a second stop |
From Belize City, Hopkins, Placencia, or the islands, add your travel time to each side of the day. ATM from the coast or the islands is a 10 to 12 hour day.
Which cave should you choose?
Choose ATM Cave if:
- Everyone in your group is fit, comfortable in water, and fine with getting completely wet.
- You want to see Maya artifacts and skeletons up close, in the place they were left.
- You have a full day and do not mind a long trip from the coast or the islands.
Choose Barton Creek Cave if:
- You are traveling with young children, older parents, or anyone with limited mobility.
- Someone in your group is nervous about tight spaces or swimming in the dark.
- You want photos of the cave.
- You want to combine a cave with Xunantunich or another Cayo stop in one day.
Some guests staying in San Ignacio do both on different days: Barton Creek first, then ATM when they are ready for the bigger challenge.
Other Maya caves near San Ignacio
ATM and Barton Creek are the best-known caves in Cayo, but not the only ones. Crystal Cave near Belmopan is a dry cave with more climbing than Barton Creek and fewer visitors than ATM. Nohoch Che'en and St. Herman's are the places to go for cave tubing. If cave tubing is on your list, read our comparison of Nohoch Che'en and St. Herman's Cave.
What to wear and bring
For ATM Cave
- Shoes that can get wet and grip well, such as hiking sandals with straps or old trainers. Flip-flops are not allowed.
- Socks to wear in the main chamber, where shoes come off.
- Quick-dry clothes that you do not mind getting wet and muddy.
- A full change of dry clothes and a towel for after the tour.
- Leave cameras, phones, and jewelry behind or with your guide.
For Barton Creek Cave
- Comfortable clothes and sandals or shoes that can get a little wet.
- Insect repellent and sunscreen for the stops outside.
- A camera, if your guide confirms photos are allowed that day.
What affects the cost
ATM tours usually cost more than Barton Creek, because ATM is a full day and NICH limits each licensed guide to small groups. The price also depends on where you start, since a pickup from Belize City, Hopkins, or the islands adds driving and sometimes a boat. Our booking pages show the current price for your pickup point and group size.

Frequently asked questions
Is ATM Cave worth it?
For active travelers, yes. ATM is one of the most memorable cave experiences in Central America, and many guests call it the best day of their trip. Barton Creek is the better choice for anyone who wants a gentle day.
Which is better, ATM Cave or Barton Creek Cave?
ATM is the bigger adventure, with skeletons and artifacts up close. Barton Creek is easier, shorter, and suitable for almost everyone. The right choice depends on your group's fitness and comfort in water.
Can I see skeletons at Barton Creek Cave?
Yes. Maya bones and pottery are visible on ledges from the canoe, although you see them from farther away than at ATM.
How old do you have to be for ATM Cave?
NICH requires children to be at least 40 inches tall. We recommend ATM for confident kids of about 8 and older because of the swim and the climbing.
Can I take pictures in ATM Cave?
No. Cameras and phones are not allowed inside ATM. Photos are usually allowed at Barton Creek.
Can I do ATM Cave and Barton Creek on the same day?
It is possible from San Ignacio but makes for a very long, tiring day. Most guests are happier doing them on separate days, or pairing Barton Creek with Xunantunich.
Can I visit ATM Cave from a cruise ship?
We do not recommend it. ATM is a long day from Belize City, and the timing is too tight for most cruise schedules. Cave tubing at Nohoch Che'en is a better shore excursion.
Is ATM open in the rainy season?
Yes, on most days. After heavy rain, the cave can close until the water drops. We check conditions and will help you reschedule if needed.
