Such castles in Colorado, Utah, and New Hampshire attract many visitors with their caves, arched entryways, passageways, and tunnels, reminiscent of a fairytale. In the evening, the ice structures light up with many colors, highlighting the surreal beauty that leaves both adults and children speechless.
The unique nature of these labyrinths lies in their building blocks, which are actual icicles. Every castle begins with 5000 icicles that the creators erect all at once. Depending on the weather, anywhere from 5 to 10 thousand icicles can be erected over the course of one day.
