Laguna Kaan Luum is a shallow lagoon off Highway 307, about 16 km by road south-west of Tulum town. Most of it is shoulder-deep, but a cenote in the middle drops to more than 80 m and is roped off. You can wade and swim in the shallows. Sunscreen, alcohol, speakers and pets are not allowed.
Laguna Kaan Luum is a shallow lagoon off Highway 307 south of Tulum, about 16 km by road from the town centre. Most of the lagoon is around shoulder-deep, with pale turquoise water. In the middle sits a cenote, a flooded sinkhole more than 80 m deep, which shows as a dark blue circle. That deep part is roped off. Swimmers stay in the shallows.
It is a short trip, and an easy one to combine with Sian Ka’an or the cenotes south of town.

We have not printed an entry price. The only dated figure we found is from 2021, and newer travel guides disagree with each other by a wide margin. Hours given by guides also vary. Bring cash pesos and go in the daytime.
Kaan Luum is not a cenote you climb down into. It is an open lagoon in the jungle, so there is no cave to climb into. The draw is the contrast: a wide ring of pale, shallow water around a single circle of very deep blue.
You can walk in from the shore, float, or sit in the shallow water. The deep centre is fenced off with rope. Food and Pleasure describes it as a protected area that visitors may not enter, and Ruptura 360 puts its depth at 82 m.
Ruptura 360’s 2021 report found free-to-use palapas and basic toilets that are not changing rooms, and no shops on site. Bring water and snacks.
The rules match those at most cenotes around Tulum:
Sunscreen chemicals have been found in groundwater around the Riviera Maya as tourism has grown. Our cenote swimming guide explains why the rule exists and what to bring instead.
Kaan Luum is open water under the sun, so the weather shapes the visit more than it does at a covered cenote. WeatherSpark’s climate averages for Tulum put the dry season from about early November to late May. March is the driest month, with about 34 mm of rain, and September the wettest, with about 159 mm. May is the hottest, with average highs around 33°C. Hurricane season runs from 1 June to 30 November, according to the US National Hurricane Center.
The lagoon is also a fallback when the sea is bad. Sargassum, the brown seaweed that washes onto Tulum’s beaches mostly between April and October, does not reach inland water. The Tulum Times lists lagoons and cenotes as the places to swim when it covers the coast. Our Tulum sargassum guide tracks the season.
Kaan Luum is off Highway 307, the main road south from Tulum toward Felipe Carrillo Puerto and Chetumal.
Our getting around Tulum guide compares cars, taxis, colectivo vans and bikes, and the Tulum cenote map shows Kaan Luum against the other swimming spots south of town.
Highway 307 south of Tulum has several stops that fit in the same half day:
| Stop | Distance from Tulum by road | What it is |
|---|---|---|
| Cenote Cristal and Escondido | About 4.8 km | Two open cenotes facing each other across the highway |
| Laguna Kaan Luum | About 16 km | Shallow lagoon with a deep central cenote |
| Cenote Angelita | About 16 km | Deep cenote for certified divers only |
| Muyil ruins, Sian Ka’an | About 30 km (INAH) | Maya site and boat trips on the lagoons |
A good order is Cristal and Escondido first, then Kaan Luum, then Muyil if you have the afternoon. Angelita is a dive site, not a swimming stop, so skip it unless you are booked with a dive centre.
The Sian Ka’an guide covers Muyil and its canal floats, and the tours below run on this road. One of them pairs Muyil and a canal drift with a swim at Cenote Escondido.
| Laguna Kaan Luum | A cenote such as Cristal | |
|---|---|---|
| Water | Wide, shallow lagoon | Clear pool in the rock |
| Depth where you swim | About shoulder-deep | Deeper water |
| Best for | Wading, children who can stand, photos | Snorkelling and swimming |
Kaan Luum suits people who want to stand in the water rather than swim. If you want to snorkel over rock and roots, pick a cenote instead. Our cenote entrance fees page lists what the others charge, and our guide to the cenotes near Tulum ranks them.

Most of the lagoon is shallow, about shoulder-deep around the edge where people swim. The centre is a cenote, a flooded sinkhole in the limestone, that sources put at 82 m or 85 m deep. That deep circle is the darker blue patch you see in photos. It is roped off, and swimmers must stay in the shallow area around it.
There is no official published fee, and the figures in travel guides range widely, from about MXN 100 in a 2021 report to several times that in newer blogs. Guides describe it as cash only with patchy phone signal, so bring enough pesos for entry and parking.
Yes, in the shallow part. The water around the edge is about shoulder-deep, and there are palapas, thatched shades, by the shore. The deep cenote in the middle is closed to swimmers. You cannot use sunscreen or body cream unless it is biodegradable, and alcohol, smoking, speakers and pets are not allowed.
About 16 km by road from Tulum town centre, heading south-west on Highway 307 toward Felipe Carrillo Puerto. Route planners give about 26 minutes; allow 30 to 35 with traffic. It is about 11 km in a straight line from Tulum's international airport, so it also fits as a first or last stop if you fly in or out of Tulum rather than Cancún.
Partly. Kaan Luum is a lagoon, a wide shallow body of water, with a cenote in its centre. The cenote is a deep vertical sinkhole where the limestone floor collapsed, the same process that formed Tulum's other cenotes. You swim in the lagoon around it, not in the cenote itself. For swimming inside a cenote, Cenote Cristal and Escondido are on the same road.
Sian Ka'an is a UNESCO World Heritage biosphere reserve of about 528,000 hectares that starts 11 km south of the Tulum ruins.
Tulum's beaches fall into two stretches.
The top things to do in Tulum are swimming in cenotes such as Gran Cenote and Calavera, 3 to 5 km from town, and walking the clifftop Maya ruins.
Cenote Cristal and Cenote Escondido are two quiet open cenotes facing each other across Highway 307, about 4.8 km south of Tulum town.
