Maximum number of fireflies visibility at Kalsubai
The Fireflies Festival is starting from May 17,2025 and will end on June 22,2025. The firefly sighting starts around May 10,2025, but barely few fireflies are visible during that time. Proper glow begins only when it drizzles slightly. If it stays dry, sightings remain low. Smoke, Light-Pollution, and noise pollution impact a lot on the glow of fireflies. Avoid campsites that promote Bonfire, BBQ and Music.
Glow is mainly seen around the Bari village base, forest patches, and trail sections before climb starts.
