INTO THE DARK · CAVES DIRECTORY
Wisconsin's cave geography splits between the Apostle Islands sea caves on Lake Superior and the limestone cavern country in the driftless southwest. The Apostle Islands sea caves are accessible by kayak in summer, and in ice years on foot across the frozen lake — with chandelier-like ice formations and the sound of the lake moving underneath. Cave of the Mounds near Blue Mounds is the state's primary show cave, a National Natural Landmark in Cambrian limestone.
Every cave listed here is on public or accessible land. Always bring three light sources, water, and let someone know your plans before entering any undeveloped cave. Temperature inside: typically 50–62°F year-round. Explore all caves on the Trek4Free map →
