Under the moonlight, the Perito Moreno Glacier rises like a wall of frozen light above Lake Argentino
Each full-moon night, the ice turns into a mirror: the white surface glows with bluish reflections, icebergs drift like fragments of the moon, and the entire landscape seems to suspend time.
Since November 2025, Los Glaciares National Park has allowed visitors to walk the boardwalks under that winter glow, during nights of the full moon. It is not a spectacle but a ceremony of light and silence. In the half-darkness, the shadows of onlookers blend with the forms of the ice; a distant crack breaks the stillness, and the echo travels across the lake like a deep breath.
From a distance, the glacier’s front —nearly 60 meters high (about 197 feet)— seems to move. Moonlight reveals sky-blue veins, deep crevices, and ridges carved by centuries of pressure. At times, a calving of ice breaks the wall: the crash echoes, the water ripples, and the reflection slowly recomposes itself.
The air carries a clean coldness, with hints of snow and wet stone. The moon, high and clear, illuminates the Andes range and casts over the ice a silvery glow that shifts with every passing cloud. Everything there is vastness and silence: a form of beauty not to be seen but breathed.
And although witnessing Perito Moreno under the full moon is a rare privilege —a scene that feels outside of time— it does not replace the daylight experience. In sunlight, the glacier reveals its full power: the blue turns intense, the calvings explode with force, and the ice unveils the life pulsing within its stillness. At night, instead, it becomes a dream—different, intimate, unforgettable.
