Underworld

Zion N.P., Utah

Underworld - The Subway is a remarkable slot canyon in the breathtaking wilderness of Zion National Park, Utah. In this beautiful area, towering sandstone walls rise dramatically, and crystal-clear waters gently flow into several emerald pools along the canyon floor. When sunlight glows through the curved passage, it illuminates the sandstone walls and creates an ethereal atmosphere, transforming the canyon into a natural masterpiece.
