A Sparkling Night at Kumbalangi
Last summer, I visited Kumbalangi village in Kerala, and its glowing waters left me spellbound. As night fell, the backwaters twinkled like a sky full of stars, a magical sight I’ll never forget.
The village was quiet, with lush green trees rustling in the breeze. At dusk, we took a boat ride, and soon, the water began to glow with tiny blue-green sparkles. These were micro-planktons, tiny creatures creating bioluminescence. Each ripple in the water sent sparkles dancing, like fireflies in the sea. The air smelled fresh, and the sound of gentle waves was soothing. I dipped my hand in, and the water glowed around my fingers, making me feel like I was in a fairy tale.
The villagers explained that this natural wonder happens when micro-planktons are active, especially on warm nights. I also enjoyed their spicy fish curry and learned about their fishing traditions. The glowing waters felt like nature’s secret light show, teaching me how even tiny creatures can create something extraordinary.
This experience showed me the beauty of nature’s surprises. Kumbalangi’s glowing waters are a treasure, reminding us to explore and protect our environment.
