The Ice Castles are back in Minnesota for a sixth installment, this time setting up shop in New Brighton. What started with a guy in Utah trying to build an ice cave for his daughter has become a massive tourist sensation, with locations popping up all over the country. Castles feature tunnels, fountains, slides, and crawl spaces, making it feel like the movie Frozen has come to life. Construction begins in November, as professional ice artisans have been growing, harvesting, and placing up to 10,000 icicles each day to create the structure, which will be lit up by LED lights once it has reached peak winter wonderland. The Ice Castles were unveiled on January 17 and will likely remian open through March—but that’s only if the weather cooperates and stays cold enough to keep the castles frozen. So, realistically, we’re saying they’ll probably be open until at least Memorial Day. Find updates and more info at icecastles.com/minnesota.
