The Apostle Islands ice caves were opened on Monday for the first time in 11 years, only the third time that access to the caves has been deemed safe, as confirmed by the National Lakeshore. WXPR PublicRadio reports that due to rapidly changing conditions, visitors are warned access may close with little notice, especially with warm temperatures or as in the case for the next few days, the ice caves will be closed starting today-Tuesday, to ensure public safety due to the upcoming winter storm. The caves may remain closed for several days while rangers evaluate ice conditions after the storm. A $5 fee is required. If visitors paid the NPS Ice Cave Fee but couldn’t get out to the caves, their purchase will be honored for a future date.The Meyers Beach parking lot is closed; access will be via county-run shuttles that will cost an additional $10 out and back to parking. The 2-6 mile round trip hike on uneven lake ice is challenging, with no shelter, water, or reliable cell service. Visitors must dress for harsh winter and potential standing water.
