A scenic colonial-era railway viaduct near Ella, ringed by jungle. Giant honey bees nest under the arches, and swarm incidents affecting visitors on the bridge have been reported and filmed in several different years.

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. News coverage (Colombo Gazette 2023, Free Press Journal 2026), a first-hand Reddit account (2024) and a visitor review describe recurring giant-honey-bee swarms under the arches across multiple years.
Visitors and even news headlines often call these “wasps” or “hornets”, but multiple independent reports identify them as giant honey bees (Apis dorsata) nesting under the arches. HornetAlert records this as bee activity, not hornets.

What visitors report

Public reports, news coverage and visitor videos describe colonies of giant honey bees beneath the arches occasionally swarming people who are walking or posing on the bridge, in some cases causing many stings and hospital visits. Commonly mentioned triggers are loud noise, sudden movement and drones disturbing the hives. Encounters appear intermittent rather than guaranteed, and the colonies are present through the year rather than in a single season.

Practical advice

  • Stay quiet and calm when passing near the colonies; loud noise can provoke a swarm.
  • Do not throw objects, fly drones, or make sudden movements near the hives.
  • If bees begin to swarm, walk away steadily, cover your head and face, and do not swat.
  • Follow any on-site warning signs and instructions from railway or local staff.
  • 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.
