Why there are wasps and hornets at Sigiriya
Sigiriya's sheer upper rock face, sheltered from rain and predators, is ideal nesting ground for large colonies of wasps and hornets. The nests hang from overhangs above the lion's paw terrace and along the upper western face, and they have been there for as long as records exist.
The colonies are usually indifferent to visitors. Problems occur when a nest is disturbed, and a large swarm on a narrow stairway can cause injuries and panic. That is why the site takes the risk seriously.
What sets them off
Wasp and hornet attacks at Sigiriya are usually triggered by disturbance. Loud noise, shouting and whistling near the upper face are commonly blamed, as are smoke, strong perfume and strongly scented sprays. Strong wind can also dislodge or agitate nests, which is why incidents tend to cluster in windy spells.
Drones are banned at Sigiriya partly for this reason: a drone flown close to the rock face is one of the fastest ways to provoke a colony.
- →Loud noise, shouting or whistling on the upper stairs.
- →Smoke, including cigarettes.
- →Strong perfume, aftershave or scented sprays.
- →Strong wind agitating or dislodging nests.
- →Drones flown near the rock face.
Wire-mesh shelters and closures
The wire-mesh shelters on the Sigiriya route, including at the lion's paw terrace, are designed for visitors to step inside during a swarm. The mesh is fine enough to keep insects out while they settle.
When the colonies are active, site staff may close the upper stairway temporarily, or stop visitors at the lion's paw terrace until conditions calm. On rare days the upper section stays shut. It is frustrating, but it is the right call, and it is one reason to allow two nights near Sigiriya rather than one.
- →Shelters sit on the route, including at the lion's paw terrace.
- →Staff may pause access to the summit when colonies are active.
- →Closures are usually temporary, but occasionally last the day.
- →Two nights nearby gives a second chance if the summit is shut.
What to do if wasps swarm at Sigiriya
If a swarm starts at Sigiriya, act quickly and calmly. Do not swat, run on the stairs or shout, which makes things worse and risks falls. Cover your face and head, move to the nearest shelter or follow staff directions, and stay inside until staff say it is safe.
If you are stung several times, seek help from staff, who can arrange first aid. Anyone showing signs of a severe allergic reaction, such as difficulty breathing or swelling of the face or throat, needs urgent medical attention.

If you have a sting allergy
Anyone with a known allergy to wasp or bee stings should take medical advice before climbing Sigiriya, carry any prescribed emergency medication, and tell their guide and companions how to use it. The nearest hospital facilities are in Dambulla, roughly 30 to 40 minutes away.
For people with a serious allergy, a visit limited to the water gardens, boulder gardens and museum, away from the upper face, is a reasonable choice.
Keeping the risk in perspective
Most visitors to Sigiriya never see a wasp swarm, and serious incidents are rare. The risk is real enough to justify the shelters and the rules, but it is not a reason to skip the climb.
Lankan Stays & Trails guides check conditions with site staff on arrival and brief groups on the shelters before the lion's paw terrace. Keeping quiet and scent-free on the upper stairs is the single most useful thing a visitor can do.
