From late April to early June, every corner of Cuc Phuong Forest seems to be bathed in rainbow light as butterflies fill the sky. Tens of thousands of delicate wings — in shades of white, yellow, jade green, and soft purple — drift gracefully through the air. In the morning sunlight, they gently land on tree branches, along streams, forming flowing, colorful trails that glide through the ancient forest.

Walking through the forest during these days feels like strolling through a shower of floral rain. With just a slight raise of the hand, a few butterflies may flutter down, trembling softly like whispers of summer. Every little corner of Cuc Phuong transforms into a vibrant painting, mesmerizing nature lovers and holding their gaze in awe.

While the days in Cuc Phuong burst with vibrant colors, when night falls, the forest glows with countless tiny sparks from little fireflies. Swarms of them gather beneath the ancient tree canopies and across the damp forest floor, creating a shimmering scene like rivers of stars flowing between earth and sky.

Venturing deeper into the forest on firefly nights feels like stepping into another world — where only the soft chirping of crickets, the gentle rustle of wind through leaves, and the mystical flicker of fireflies remain. Each step feels like entering a fairyland, lighting up the soul with childlike wonder and a nostalgic memory of dazzling summer nights.

Every summer, Cuc Phuong’s festival of butterflies and fireflies brings back nature’s magical moments. Amid the pace of modern life, the chance to immerse oneself in nature and witness its radiant colors and enchanting lights is a precious gift that Cuc Phuong offers to every visitor who finds their way here.
