Discover Parfrey’s Glen: A Unique Natural Treasure in Wisconsin

Parfrey’s Glen holds the distinction of being Wisconsin’s very first State Natural Area—and for good reason.

 Located just a few miles east of Devil’s Lake State Park, it’s one of the most popular natural sites in the region. Open daily from 6 a.m. to 8 p.m., Parfrey’s Glen offers visitors a glimpse into the state’s ancient geological past and fragile natural beauty.

A Glimpse into Nature’s History

At its deepest point, Parfrey’s Glen reaches nearly 100 feet. A cool, clear stream runs through the heart of the gorge, framed by sandstone walls filled with embedded quartzite pebbles and boulders—sometimes referred to as “plum pudding” stone due to its unique texture. These rock layers were once part of an ancient beach, now transformed by time and water.

Because the area is home to several threatened plant and insect species, visitors are required to stay on the designated trail. The path is an out-and-back hike that runs approximately 0.8 miles from the lower parking lot to the top of the glen.

Environmental Impact & Trail Conditions

Over the past two decades, Parfrey’s Glen has seen significant changes—due both to powerful flooding and increased foot traffic fueled by social media exposure. Frequent floods have washed away old bridges and trails, making the original route from the 1980s and 90s nearly unrecognizable.

In response, the Wisconsin DNR has stopped repairing the trail within the gorge itself. Hikers heading to the waterfall now need to navigate through the stream and over rough stones. The stone steps and viewing area near the falls have deteriorated; some steps are missing, and part of the viewing platform has collapsed.

Visitors are allowed to wade through the stream up to the pool below the waterfall—but not beyond it. Despite this, some still go off-trail, contributing to erosion and further damage to the delicate environment.

Visitor Guidelines & Rules

To help protect this unique natural space, all visitors must follow these important rules:

 Stay on designated trails
 Do not enter closed areas
 Do not hike beyond the waterfall
 No pets allowed
No rock climbing, rappelling, or off-trail exploring
 No food or drink inside the glen
 Picnicking is allowed only near the parking area
 Do not pick plants or collect anything from the area
 A valid Wisconsin State Park vehicle sticker is required

Getting There

Parfrey’s Glen is located about 4 miles east of Devil’s Lake State Park. From Baraboo, take Hwy 113 south and turn left onto County Road DL. The entrance will be on your left a few miles down. It’s easy to miss—if you reach the 4-way stop near the Old Schoolhouse Restaurant, you’ve gone too far. Just turn around and head back about half a mile.
