A UNESCO-listed rock fortress rising sheer from the central Sri Lankan plain. Giant honey bees colonise the rock face; on-site signs ask visitors to stay quiet, and the site is closed temporarily when the bees swarm.

Confirmed hotspot. This location is classified as a Confirmed Hotspot based on recurring independent reports, reports from multiple years or additional supporting evidence. Current activity can still vary. Authoritative reporting (Mongabay 2022) plus visitor accounts and permanent on-site warning signage document recurring giant-honey-bee swarms on the rock across years, including a 2010 management intervention.
On-site signs and visitor accounts use “hornets/wasps”, but the insects are authoritatively giant honey bees (Apis dorsata) that colonise the rock face. HornetAlert records this as bee activity, not hornets.

What visitors report

Visitor accounts, travel reporting and site signage describe giant honey bee colonies on the rock that can swarm when disturbed by noise, movement or crowds along the climbing route. Management measures include warning signs asking for quiet, bee-proof shelters on the ascent and temporary closures during swarms, with protective clothing sometimes provided. Reports span multiple years, and the colonies are a recurring feature of the site rather than a one-off event.

Practical advice

  • Keep your voice down and move calmly near the colonies, especially on the stairways.
  • Do not throw objects, fly drones, or bang on the railings near the hives.
  • If bees begin to swarm, use the bee-proof shelters or move away steadily; cover your head and do not swat.
  • Follow the on-site warning signs and staff guidance, including any temporary closures.
  • If you have a known allergy to bee stings, carry your medication and take extra care.

Seasonal Hotspots highlight places where visitors repeatedly report wasps, hornets, bees or other stinging insects. Reports are based on public visitor accounts and community observations, not scientific surveys or official safety warnings. Insect activity can vary by season, weather and local conditions.
