Niagara Cave

· Harmony, MN

Why you should go…

Niagara Cave is a limestone cavern in Fillmore County near Harmony, Minnesota, open as a show cave since 1934. Guided tours descend roughly 200 feet past fossils, stalactites and stalagmites, an underground stream, and a 60-foot waterfall; the privately owned cave draws 25,000 to 30,000 visitors a year.

Good to know

General tours guidance

Habits that pay off across this whole category, not rules for this one venue. Always check the official site for the specifics.

  • Confirm the meeting point

    It is often a corner, a lobby, or a dock rather than the address you searched for. Check it the night before.

  • Small groups fill first

    In high season the intimate departures sell out well before the big-bus options do.

  • Ask how much is on foot

    Knowing how much of the route is walking, standing, or outdoors tells you what to wear and carry.

  • Read the weather policy

    Cancellation windows and rain rules vary by operator, and they are easier to find before you pay than after.
