Winter Weather Information
Sandstone sea caves formed by centuries of freezing, thawing, and wave action are a favorite travel destination in summer and winter. Summer days allow kayakers to "island hop" and, on a calm day, to navigate deep into the caves to explore rock formations. In winter, spectacular ice formations hang from the caves that entice walkers, snowshoers, and cross-country skiers to discover the ever-changing, cathedral-like formations. Travelers can access the Apostles in a variety of ways: a guided cruise, an island shuttle, sailing or power boating, kayaking, or private boat charters.
Madeline Island, the largest of the Apostle Islands and the only island with commercial development and a year-round population, is not a part of the national park property, but can be accessed by ferry most of the year and via an ice road in winter.
