When people start planning a safari in Yala, there are usually one or two animals already in their minds. For many, it is the leopard. For others, it is an elephant. And then there are people who have read about the Sri Lankan sloth bear and quietly hope that, somehow, they might be lucky enough to see one.
There is nothing wrong with coming to Yala hoping for those animals. They are some of the most exciting wildlife Sri Lanka has to offer. But there is something we think is worth understanding before you choose a safari in Block 5 or Block 6. You are not entering a place where the animals are waiting along the road in a fixed order.
You might spend the first hour looking across open grassland and see spotted deer, peafowl and birds everywhere, but no large mammals. Then you find a group of elephants. A little later, you stop beside a waterhole and realise there are crocodiles lying almost completely motionless along the bank. You may hear langurs calling somewhere in the trees and start wondering what they have noticed. And perhaps, if you are very fortunate, something much harder to find suddenly appears. A sloth bear beneath a Palu tree. A leopard crossing the track.
Those moments are part of what makes a safari interesting, but they are also the reason we don't like giving people a simple list of animals and telling them what they will see. Wildlife changes from day to day. Water levels change. Food changes. Animals move between habitats. The weather changes. Some species are active at certain times of the day and almost impossible to find at others.
And Blocks 5 and 6 have their own character within this larger Yala ecosystem. They are not simply quieter versions of Block 1. The habitats are different in places, the visitor pressure is generally lower, and the wildlife experience can feel quite different. Some animals are regularly encountered. Others are occasional. A few are genuinely difficult to find, even when you know they live there.
That difference is important because we would rather tell you honestly what you might realistically encounter than give you a long list of every species that has been recorded somewhere in Yala. Yala National Park supports around 44 species of mammals and more than 200 species of birds, across dry forest, scrub, grassland, tanks, wetlands and other habitats. The park is also recognised as an Important Bird Area.
But knowing that a species lives in Yala is not the same as saying you are likely to see it during a four or six-hour safari.
So, what can you actually expect in Yala Block 5 and Block 6?
The answer depends on the animal, the habitat, the season, the conditions on the day and, as always with wild animals, a fair amount of luck.
And perhaps the best place to start is with the animal most people are already thinking about.
Sri Lankan Leopard
Let's start with the animal most people are probably thinking about.
Leopards are present in both Block 5 and Block 6, but this is also where we want to be particularly honest.
A leopard sighting in Block 5 is possible, but it is uncommon and unpredictable compared with the famous leopard areas of Block 1. In Block 6, sightings are rare, and we would not recommend choosing the block primarily because you want to see a leopard.
That doesn't mean there are no leopards there.
It simply means that knowing an animal lives in an area and actually finding it during a few hours in a safari vehicle are two very different things.
A leopard can be somewhere nearby and you may never know it is there. It could be resting in thick vegetation, moving through an area away from the road or simply active at a time when you are somewhere else.
If seeing a leopard is the main reason you are coming to Yala, we would rather have that conversation with you before you book. Block 1 has a much stronger reputation for leopard sightings, and there is a reason for that.
If you are more interested in exploring a quieter part of Yala and are happy to accept that a leopard may not become part of your day, then Block 5 or Block 6 can offer a very different experience.
And if a leopard does happen to appear, there is another difference worth mentioning. The lower vehicle pressure in these blocks can sometimes allow for a much quieter encounter. There is never a guarantee that other vehicles won't arrive, but you are less likely to experience the same concentration of vehicles associated with the most famous leopard sightings in Block 1.
Sri Lankan Elephant
Elephants are a different story, although there is still a noticeable difference between Blocks 5 and 6.
In Block 5, elephant sightings are occasional and quite variable. You can have a wonderful elephant encounter, but we would not tell you to expect elephants on every drive.
In Block 6, the chances are generally better, although we would still describe elephant sightings as variable rather than regular or guaranteed.
Where elephants spend their time changes with water, food, weather and the season. During drier periods, water becomes particularly important, and this can influence where family groups and individual bulls move through the park.
You may come across a family group feeding in the scrub, a few elephants near a water source or a solitary bull moving through the landscape.
And this is one animal we really don't like treating as something you simply stop for, photograph and leave.
If you find an elephant herd feeding quietly, there can be a lot more to watch. You might notice the adults positioning themselves around younger animals, calves playing with each other, or one elephant suddenly becoming alert while the others continue feeding.
Sometimes the whole herd changes direction because one of the older females has decided it is time to move.
Those small behaviours are often what make an elephant encounter memorable.
Sri Lankan Sloth Bear
If there is one animal that can make a Block 5 safari particularly special, it is the Sri Lankan sloth bear.
But we would put sloth bears firmly in the uncommon and highly unpredictable category.
They are not an animal you should expect to see simply because you are visiting Block 5. Even when conditions seem good, a bear can be moving through dense vegetation only a short distance away and remain completely invisible.
One of the things we pay particular attention to is the availability of Palu fruit. Palu, Manilkara hexandra, is one of the characteristic trees of Sri Lanka's dry zone, and when it produces fruit, that can create interesting feeding opportunities for many animals, including sloth bears.
From our own experience, May and June can be particularly interesting because of the Palu fruiting season. Rain can also change the situation because softer ground around termite mounds can make it easier for bears to dig for termites, which are an important part of their diet.
But none of this means a bear will appear.
We are simply looking at the conditions and signs that might tell us where it makes sense to spend some time.
Fresh tracks.
Feeding marks.
Fruiting trees.
Termite activity.
The condition of the ground.
Even after finding all the right signs, we may never see the bear.
That is exactly why we think a sloth bear sighting should feel special rather than something you were expecting as part of the safari.
Block 6 can also hold sloth bears, but we would consider sightings there rare and highly unpredictable. It is certainly not a species we would tell you to choose Block 6 specifically to find.
Wild Water Buffalo
Wild water buffalo are another important part of the Yala landscape.
They can be encountered around tanks, wetlands, grassland and other areas where water and suitable grazing are available. From a distance they can sometimes look similar to domestic buffalo, but watching genuinely wild buffalo behaving naturally is a very different experience.
If you spend a little time with them, you can start noticing the social behaviour within the herd, how individuals react to one another and how the group responds when something approaches.
They are also one of those animals that can easily be overlooked because everyone is scanning the landscape for a leopard.
Personally, I think that is a mistake.
Sometimes the animals you see more regularly are the ones that become most interesting when you stop and actually watch them.
Spotted Deer
Spotted deer, or chital, are among the animals you are much more likely to encounter during a safari in both Blocks 5 and 6.
They are widespread throughout Yala and are an important prey species for predators such as leopards.
But there is more to them than simply saying that they are common.
Watch a herd for a few minutes.
Some animals may continue feeding while others remain alert. Suddenly one deer raises its head. Another looks in the same direction. The whole group becomes slightly more watchful.
Sometimes they are reacting to something you haven't noticed yet.
An alarm call can also change the mood of the entire herd.
This is one of the things we enjoy about guiding. A common animal can become interesting when you understand what it is doing and why.

We plan everything personally and reply on WhatsApp, usually within a few hours.
Mugger Crocodile
Mugger crocodiles are regularly encountered around suitable water sources in Yala.
They are also surprisingly easy to miss.
You can drive past a muddy bank and initially see nothing more than a few pieces of wood lying beside the water. Then you realise that one of those "logs" has eyes.
Crocodiles spend long periods lying motionless, either basking in the sun or waiting beside the water.
The tanks and wetlands in Blocks 5 and 6 can therefore be good places to slow down and look carefully.
They are another good example of why a safari is not always about driving from one major sighting to another. Sometimes you simply have to stop and look.
Wild Boar
Wild boar are an interesting case because the situation in Yala has changed considerably over the years.
They used to be a common sight in the park. People who spent time in Yala years ago would often talk about seeing wild boar regularly and sometimes in good numbers.
That has changed.
A serious disease outbreak affected Sri Lanka's wild boar population in recent years, with wild boar deaths reported in Yala and other areas. African swine fever virus was subsequently detected in a wild boar sample from Yala.
From what we are seeing in the field now, wild boar are rare compared with what they used to be.
Honestly, on some safaris it can feel like you have a better chance of seeing a leopard than a wild boar. That is quite a change from the Yala many older guides remember.
So if you read an old wildlife guide describing wild boar as one of the common animals of Yala, keep in mind that the situation has changed.
Golden Jackal
Golden jackals are present in Yala, but we would also describe them as rare sightings rather than a regular safari animal in Blocks 5 and 6.
When you do find one, it can be a very nice encounter.
They may appear briefly in open grassland, move along a track or disappear into the scrub almost as quickly as they arrived.
Sometimes you see a pair or a small family group.
But again, we would never tell you to expect one.
Grey Langurs and Other Monkeys
Grey langurs are much easier to come across and can be regularly encountered in both blocks.
They are also worth paying attention to for reasons beyond simply watching monkeys moving through the trees.
Langurs are very vocal, and changes in their behaviour can sometimes give you clues about what is happening nearby.
An alarm call does not automatically mean there is a leopard. It could be another predator, a large bird of prey or something else they consider a threat.
But when a whole group suddenly becomes alert and starts looking in the same direction, it is worth paying attention.
The forest often gives you little clues before you see the animal responsible.
Birds of Yala Block 5 and Block 6
If you are interested in birds, I would strongly recommend not treating them as something to look at only when the larger mammals are quiet.
Yala supports a remarkable variety of birdlife, including resident species, migrants and Sri Lankan endemics. The different habitats are a big part of the reason. Wetlands support waterbirds, while dry forest, scrub and grassland bring a completely different collection of species.
Depending on the habitat and season, you may come across painted storks, herons, egrets, black-headed ibises, Asian openbills, spoonbills and different waders around wetlands.
Then there are the forest and open-country birds.
Bee-eaters.
Rollers.
Hornbills.
Peafowl.
Kingfishers.
And many smaller species that are very easy to miss if you are concentrating only on elephants and leopards.
For birdwatchers, this is one of the biggest reasons to slow down. A bird may sit quietly in a tree for only a few seconds before flying away, and some species are much easier to hear than see.
Raptors
Yala is also a very good place to pay attention to birds of prey.
Crested serpent eagles are among the raptors you may encounter, along with species such as changeable hawk-eagles, Brahminy kites and white-bellied sea eagles.
Raptors give you another way of reading the landscape.
A bird sitting on a high branch may be scanning the grassland below. Another may be circling above a wetland. Some use the open areas around tanks and reservoirs, while others spend more time around forest edges.
If you enjoy photography, they can also be rewarding subjects because they are often more visible than a leopard hidden somewhere in thick vegetation.
Reptiles and Smaller Wildlife
There is also a lot happening below the level of the large mammals.
Monitor lizards are regularly encountered in suitable habitats, and Yala supports a wide range of reptiles, amphibians and smaller animals.
You may notice a monitor lizard crossing the track, a turtle around a water source or smaller creatures moving through the vegetation.
We don't want to turn this article into a list of every species recorded in Yala. That would give you a long catalogue without telling you much about actually experiencing the park.
The important thing is that the wildlife of Yala is much broader than the animals that appear on safari brochures.
So what are you actually most likely to see?
There is no honest percentage we can give you for every species in Blocks 5 and 6.
We don't have a sufficiently large, standardised dataset from our own safaris to say that you have a precise percentage chance of seeing an elephant, leopard or sloth bear on any particular drive.
And we don't think it is useful to invent one.
Instead, this is how we would describe the wildlife from our practical experience:
| Wildlife | Block 5 | Block 6 |
|---|---|---|
| Sri Lankan Leopard | Uncommon and unpredictable | Rare |
| Sri Lankan Elephant | Occasional and variable | Better chance, but still variable |
| Sri Lankan Sloth Bear | Uncommon and highly unpredictable | Rare and highly unpredictable |
| Wild Water Buffalo | Regularly encountered | Regularly encountered |
| Spotted Deer | Common | Common |
| Mugger Crocodile | Regular around suitable water | Regular around suitable water |
| Wild Boar | Rare today | Rare today |
| Golden Jackal | Rare | Rare |
| Grey Langur | Regular | Regular |
| Birds | Excellent variety | Excellent variety |
| Raptors | Regular depending on habitat | Regular depending on habitat |
These descriptions are deliberately broad.
A "regular" animal can still be absent during your particular drive.
A "rare" animal can appear five minutes after you enter the park.
That is simply how wildlife works.
What makes Blocks 5 and 6 interesting?
For us, it comes back to the fact that the safari doesn't have to revolve around one particular animal.
If you enter Block 5 hoping for a leopard and spend the entire safari thinking about nothing else, you could miss a sloth bear feeding beneath a Palu tree, an elephant herd moving through the scrub, a crocodile lying beside a reservoir, a jackal crossing the grassland or a raptor sitting quietly above the track.
The same applies even more to Block 6.
We would not recommend Block 6 to someone whose only goal is to see a leopard.
We would recommend it to someone who is interested in experiencing a quieter part of the Yala landscape and is happy to see what the day brings.
And that can sometimes lead to the most memorable encounters.
You might leave the gate hoping for an elephant and end up spending twenty minutes watching a crocodile.
You might stop for a bird and suddenly notice that all the deer nearby have become alert.
You might find fresh tracks without ever seeing the animal that left them.
And perhaps, when you were not expecting it at all, a sloth bear appears beneath a Palu tree.
Or a leopard crosses the track for a few seconds.
That is the part of wildlife that no species list can really explain.
You can know what lives in Yala. You can understand the habitats. You can learn the seasonal patterns. You can choose the block that suits your interests.
But once you enter the park, the animals still decide what happens.
And that is exactly why we think the best way to approach Blocks 5 and 6 is to come looking for wildlife as a whole, rather than arriving with a checklist that has only three animals on it.
Planning a safari in Yala Block 5 or Block 6?
We plan each safari personally and are happy to talk through what you are hoping to see, the time of year you are visiting and which block we think would suit you best.
If your priority is a leopard, tell us. If you are more interested in elephants, sloth bears, birds or simply having a quieter wildlife experience, tell us that too. We will give you our honest view before you book, including if we think another option would suit you better.
