Eden Prairie Ice Castle
Two years after building an ice castle next to the Mall of America, the Utah-based company behind it returns to Minnesota in a new location: Eden Prairie's Miller Park. Instead of using blocks, Utah ice sculptor Brent Christensen uses icicles and water to create the glacier-like structure, complete with walls, tunnels, archways and thousands of colored LED lights. New additions include appearances by the "Enchanted Frozen Sisters" and an ice princess, as well as fire performances. (Daily through March 7. $6.95-$12.95, $25 season pass. Miller Park, 17970 E. Miller Pkwy., Eden Prairie. www.icecastles.com/ep.)
City of Lakes Loppet
Since 2002, the Loppet has become one of Minneapolis' favorite winter traditions for experts and amateurs. Thousands of skiers, snowshoers, skijorers, dog sledders and fat bikers will gather across the Chain of Lakes for a series of "loppets" — competitive and noncompetitive treks — as well as the popular Luminaria Loppet on Jan. 31 and races from Theodore Wirth Park to Lake Calhoun on Feb. 1. The weekend also includes a snow sculpture contest, a Surly beer garden, food trucks and opening night fireworks. (Jan. 30-Feb. 1. $15-$120 registration, spectators free. 1301 Theodore Wirth Pkwy., Mpls. www.loppet.org.)
Art Sled Rally
The Art Sled Rally — a uniquely Minnesotan tradition of building a sliding contraption and then riding it down a snowy slope in Powderhorn Park — returns for its eighth year. The free community event encourages kids of all ages to create an artful sled out of cardboard, wood, steel or anything else with sliding capability. The only requirement: It must be crafted in a "fashionable, ridiculous or artistic way." Get help building yours in advance at Bedlam Design Center (10 a.m.-3 p.m. Sat. -Sun., 5-9 p.m. Tue. and next. Thu., 2714 E. 27th St., Mpls.). To secure a slot in the lineup, arrive at Powderhorn's western slope by 1:30 p.m. Jan. 31. (2 p.m. Jan. 31. Free. Powderhorn Park, 3400 15th Av. S., Mpls. www.artsledrally.com.)
Polar Plunges
Among the craziest things Minnesotans do: diving into freezing water for sport. The annual Polar Plunge pops up at lakes across the state, with thousands jumping in to raise money for Special Olympics Minnesota. The Lake Calhoun edition on March 7 is the largest, with additional activities including snow volleyball, an ice carving contest, a 5K walk/run and ice bowling. (Jan. 31-March 21. www.plungemn.org.)
