The Apostle Islands ice caves open on only ~2% of days — and there's no parking at the trailhead
The mainland ice caves at Apostle Islands National Lakeshore (Meyers Beach, near Bayfield) are reached by walking miles across the frozen surface of Lake Superior — and per the NPS they've been accessible on only 2% of all days from 2000-2023, with the prior opening a brief nine-day window in 2015 before 2026. There is no parking at the trailhead; visitors use off-site lots and a county shuttle, and access can close with little notice when the ice breaks up (it did, mid-February 2026, after a storm). Treat a 'maybe-open' year as a bonus, never the reason you point your rig north.
