There’s more to the Dells than water parks. For instance, the area is full of history, some of which you can experience firsthand. That’s definitely the case with what’s known by locals as The Grotto, an abandoned cave with a colorful history.

Often overlooked by Dells visitors, The Grotto is a roadside attraction worth pulling over for.

At first glance, it just looks like a graffiti-covered cave; however, it boasts a history that’s as colorful as the spray paint covering its walls.

The cave’s origins, other than the fact that it’s man-made and dates back to the early 1900s, are rather obscure.

More than a century ago, it served as a saloon, making it one of the first bars in the Dells.

Long abandoned, the cave serves as a reminder of what once was.

There’s even signage that provides some information about the surrounding area.

Situated along the roadway, The Grotto couldn’t be easier to access.

As an added perk, Timme’s Mill County Park is right by the cave.

Accessing the park requires just a short trek across the road and down a flight of stairs.

The park is named after a flour mill that was once located on Dell Creek.

Today, the park provides a canoe and kayak launch to Mirror Lake.

There’s also a spacious platform, so you can easily soak in the scenic surroundings.
