Marble Caves of Chile — a natural labyrinth formed over 6,000 years by waves and wind.
The most unusual feature of these caves is their walls. The marble's color changes depending on the time of day and season: from milky white at dawn to deep turquoise and blue at midday.
Interesting fact: The cave's hues depend not only on light but also on the water level of Lake General Carrera. When the water rises, it reflects more sky, creating an effect of "picturesque galleries" carved by nature itself.
