Winter transforms the Elroy-Sparta Trail into a snowy wonderland, and while the iconic tunnels may be off-limits during the cold season, a trip to see Tunnel 3 sealed up for winter is a simple, magical experience you won’t want to miss. We visited after a fresh snowfall had blanketed the area with nearly a foot of powder, the air thick with soft, swirling flakes that added an extra layer of enchantment to our trek. As we strapped on our snowshoes and set out toward Tunnel 3, we found ourselves surrounded by the quiet beauty of snow-covered trees, gently bubbling streams, and a sense of deep winter stillness that only the Wisconsin woods can deliver.
These tunnels are in the heart of Wisconsin’s Driftless Region. Getting to Elroy-Sparta Tunnel 3 is pretty straightforward. Just head south from Sparta along State Route 71. About two to three miles down, look for Kenya Avenue. It’s a little unassuming spot, but it offers limited parking and puts you just a short hike from the massive wooden doors that bar the entrance to the tunnel each winter. The walk is manageable and definitely worth it, with snowy landscapes stretching out on either side and small, bubbling streams lining parts of the trail. The water peeking out from under thin sheets of ice seemed almost alive, a soft trickling sound in the background adding a unique calm to the atmosphere.
As for the tunnel itself—there’s something breathtaking about the sight of those tall wooden doors standing strong against the snow, keeping their secrets safe until spring. Although the tunnels are closed in winter, it’s for a good reason: these passageways are a sanctuary for bats, who hunker down inside to hibernate through the cold months. The Elroy-Sparta tunnels, especially Tunnel 3, offer a unique habitat for species like the little brown bat, which are essential to our ecosystem. Protecting their hibernation space helps preserve this fragile population, which has been challenged in recent years by white-nose syndrome and other environmental pressures. So while we can’t explore the tunnels themselves, knowing they serve as a winter retreat for these nocturnal creatures somehow makes the visit even more meaningful.
For those looking to capture the experience, Tunnel 3 in winter is a photographer’s dream. The contrast of dark wood against white snow, the gentle curve of the trail, and the mix of shadows and light filtering through the trees all come together to create a scene that’s nothing short of magical. This tunnel, in particular, is known as one of the easier ones to access, making it a great option if you’re looking for a winter hike without too much of a challenge. With snowshoes on, you’ll have solid footing, and the gentle trek allows you to fully take in the surroundings without rushing.
As we stood by those doors, taking in the scene, it was hard not to feel like we’d stumbled into some hidden part of winter’s story. The Elroy-Sparta Trail may be known for its summer biking, but if you’re up for a quieter, more contemplative experience, a winter visit to Tunnel 3 offers a slice of serenity you won’t soon forget.
WeWisconsin Tip:
If you plan to check out Tunnel 3 this winter, arrive prepared with layers, snowshoes, and maybe a thermos of something warm. And for the best lighting for photos, aim for late morning or early afternoon when the winter sun peeks through the trees just right!
