Most people who visit Sri Lanka for a safari know some basics about elephants. They know they are large. They know they can be dangerous. They know to keep a distance.
But very few know about musth. And musth is one of the most important things to understand if you are spending time in areas where wild elephants live, either inside a national park or on the roads around them.
What musth is
Musth (pronounced with a soft "t", from the Urdu word for intoxication) is a periodic condition that affects adult male elephants. During musth, a male's testosterone levels rise to levels that are 60 times higher than normal.
The physical signs are visible if you know what to look for. The temporal glands, located on the sides of the head between the eye and ear, become swollen and secrete a dark, strongly-scented fluid. This secretion is visible as a wet, dark stain running down the side of the face. The male's urine also changes, often dribbling continuously in a way that does not happen outside of musth.
The behavioural signs are harder to miss. A male in musth is highly agitated, aggressive, and reactive. He holds his head higher. He moves with a particular deliberate energy. He is easily triggered by perceived challenges, whether from other elephants or from humans and vehicles.
Why it matters outside the parks
Inside a national park, the vehicles, the distances maintained by good drivers, and the experience of the guides provide a reasonable level of safety even around bulls in musth. You observe from a distance. You do not approach.
Outside the parks is where musth becomes a serious safety concern.
Male elephants in musth wander alone, often long distances. They move at night through corridors that pass through villages, farmland, and tourist areas. A bull in musth who is moving along a forest road at 2am is genuinely dangerous to anyone in that area on foot or on a small vehicle.
This is one of the main reasons why walking near elephant corridors in darkness, whether early morning hikes to attractions like Sigiriya's Lion Rock or late-night journeys between hotels in forest areas, carries real risk. You cannot see a musth bull in the dark until you are very close to him.
How long musth lasts
Musth can last anywhere from a few weeks to several months. Older, larger bulls tend to experience longer periods of musth. During that entire period, the animal remains reactive and potentially dangerous.
When musth ends, the male's behaviour returns to its normal state. But you have no way of knowing from a roadside encounter whether a male you are looking at is in musth, ending musth, or nowhere near it.
What to do if you encounter a bull elephant
In a vehicle, inside the park: stay still, engine off, at a safe distance. Do not try to drive around the animal. Do not make sudden movements or loud noises. Wait for the elephant to move of its own accord.
On a road outside the park, on a bike or in a tuk-tuk: stop immediately. Do not accelerate past. Turn off bright lights if possible. Do not honk. Wait.
If the elephant starts moving toward you: back away slowly if in a vehicle. If on foot, move away quietly and keep moving. Do not run, which can trigger a chase response. Put solid objects between yourself and the animal if possible.
The most important thing is to stay calm and give the animal space and time. Most encounters do not escalate if the human does not make them worse.
Why this does not have to be frightening
Understanding musth is not about being afraid of elephants. It is about understanding the animal you are dealing with.
Elephants in musth are not being evil. They are not targeting humans specifically. They are in a physiological state that makes them reactive to perceived threats. If you do not present yourself as a threat, the risk is significantly lower.
I have been around thousands of elephants over years of guiding. The vast majority of encounters, even with bulls in musth, resolve without incident when the human stays calm and keeps appropriate distance.
The danger comes from not knowing, not from elephants themselves.
