Quick answer
Yala National Park has two crocodiles: the mugger crocodile, found in almost every freshwater tank and waterhole, and the larger saltwater crocodile, found in the coastal lagoons and river mouths. Water monitors and land monitors are common along the tracks, star tortoises live in the scrub, and snakes include the Indian python, Russell's viper and spectacled cobra. Crocodiles are seen on nearly every drive; snakes are rarely seen from a jeep.

- Mugger crocodiles live in nearly every freshwater tank and waterhole in Yala and are seen on almost every drive.
- Saltwater crocodiles, the larger and more dangerous species, live in Yala's coastal lagoons and river mouths.
- Water monitors, which can exceed two metres, are common at Yala's waterholes, while smaller land monitors keep to the dry scrub.
- The Indian star tortoise lives in Yala's scrub and is protected; it should never be picked up or taken.
- Snakes such as the Indian python and Russell's viper live in Yala but are rarely seen by visitors who stay in the jeep.
Yala's two crocodiles
Yala National Park holds both of Sri Lanka's crocodiles. The mugger, or marsh crocodile, is the common one: broad-snouted, usually two to three metres long, and found in almost every freshwater tank and waterhole in the park. In the dry season, muggers crowd into shrinking pools and are impossible to miss.
The saltwater crocodile is larger and keeps to the brackish lagoons and river mouths near the coast. It is the more dangerous of the two, and the reason no one swims in Yala's lagoons. Sightings are less frequent but often more impressive.
- →Mugger crocodile: freshwater tanks and waterholes, seen on almost every drive.
- →Saltwater crocodile: coastal lagoons and river mouths, larger and less often seen.
- →Best time: the dry season, roughly June to September, when water is scarce.
Water monitors and land monitors
Two monitor lizards live in Yala. The water monitor is the larger, sometimes more than two metres long, and is seen at waterholes, swimming or basking on the banks. The land monitor is smaller and keeps to the dry scrub, often crossing the tracks or climbing trees.
Both are scavengers and hunters, eating eggs, carrion, fish and small animals. Water monitors are often seen near crocodiles, scavenging what the crocodiles leave.
Star tortoises and sea turtles
The Indian star tortoise lives in Yala's dry scrub, its domed shell patterned with yellow stars. It is protected, and the illegal pet trade has hit wild populations hard. If you see one on the track, enjoy it from the jeep.
Sea turtles nest on Yala's beaches, part of a coastline that also includes the nesting beaches at Rekawa to the west. Visitors do not see nesting inside the park, but the beaches are part of why the coast is protected.
Snakes in Yala
Yala has many snakes, including the Indian python, Russell's viper, the spectacled cobra and the common krait, along with many harmless species. Snakes keep out of sight by day, and visitors in jeeps rarely see them.
Occasionally a python is seen crossing a track or coiled in a tree, and that is a sighting to treasure. Snakes are only a concern when walking, which visitors do not do in the park except at designated stops.
- →Indian python: occasionally seen crossing a track.
- →Russell's viper: present but rarely seen; dangerous on foot.
- →Spectacled cobra: present; usually moves away.
- →Safety: stay in the jeep except at designated stops.
Staying safe around Yala's reptiles
Reptiles pose little risk to visitors who follow the park rules. Stay in the jeep, never put a hand or foot in the water at designated stops and keep well back from lagoon edges, where saltwater crocodiles may lie unseen.
Around lodges near the park, walk with a torch at night and wear closed shoes. Lankan Stays & Trails briefs every safari guest on these points; for snakes and reptiles across Sri Lanka, see our island-wide reptile guide.

Frequently asked questions
Are there crocodiles in Yala?
Yes. Yala has mugger crocodiles in nearly every freshwater tank and waterhole, and larger saltwater crocodiles in the coastal lagoons and river mouths. Muggers are seen on almost every drive, especially in the dry season when they crowd into shrinking pools.
What is the difference between a mugger and a saltwater crocodile?
The mugger is broad-snouted, usually two to three metres long, and lives in fresh water. The saltwater crocodile is larger, with a narrower snout, and lives in brackish lagoons and river mouths. In Yala, the saltwater crocodile is the more dangerous of the two.

How big are the monitor lizards in Yala?
Water monitors in Yala can exceed two metres in length and are seen at waterholes, swimming or basking. Land monitors are smaller, usually under a metre and a half, and keep to the dry scrub. Both are common.
Can you swim in Yala's lagoons?
No. Swimming is not allowed in Yala, and the coastal lagoons hold saltwater crocodiles, the more dangerous of Sri Lanka's two species. Stay well back from water edges at designated stops, and treat the beaches as a view, not a place to bathe.
