A Complete Guide to the Caves in Minnesota

Minnesota is a state known for its beautiful landscapes and breathtaking lakes. It also has six distinctive national parks that enhance the state’s natural features.

But did you know that Minnesota also has one of the best karst landscapes in the United States? It features caves that are popular amongst locals who love spelunking.

Before we explore the best caves in Minnesota, let’s get a little background on the history of these caves.

Why Are There so Many Caves in Minnesota?

In Minnesota, natural and human-made caves have been used for shelter by indigenous American tribes and later by European settlers.

The southeast and central regions of the state are where most of the prominent caves are found. Most of Minnesota was buried under glacial sediment residues, making the caves not very obvious. However, the earlier mentioned regions are where erosion removed the cover of sediments, revealing the karst landscape features.

If you’d like to learn more, Minnesota’s history of cave formations was extensively researched in this paper from the University of Minnesota.

1. Waká? Tipi or Carver’s Cave

Waká? Tipi, commonly called the Carver’s Cave comprises important historic caves. However, there isn’t much space to explore since most of the cave was destroyed by railroad industrialists back in 1862.

The cave entrance is situated at the base of Daytona’s Bluff, near the Mississippi River. Currently, the cave doesn’t have more than a crawl space as most of the area is taken up by an underground lake. That doesn’t stop it from being an important historical site and tourist attraction.

2. Salt Caves

While natural caves are perfect for adventure and history enthusiasts, salt caves are made for people who just want to have a day off to unwind and relax. These commercial caves aren’t technically caves, but they have an ambiance that is similar to the feeling of being in natural caves.

Salt cave centers offer halotherapy (also known as salt therapy) services, an alternative treatment that involves breathing in air that’s saturated with small particles of salt and is said to improve your breathing.

The St. Croix Boom Site in Stillwater is an interesting site that offers a look at the state’s history. The area is a well-known picnic spot and leads down to a river that is extensively used for activities like fishing, boating, and swimming.
