The Lost Forty: Hiking Through Minnesota’s Rare Old-Growth Forest
The Lost Forty offers a rare glimpse into Minnesota’s untouched old-growth forest, a silent world of towering pines and centuries-old hardwoods. This hike invites adventurers to experience nature’s endurance with easy terrain and rich seasonal shifts.
Trail Tips
Hydrate and Pack Light
Though the trail is short, bring at least 1 liter of water and light snacks to stay energized. The forest’s cool shade can mask dehydration.
Wear Sturdy Footwear
Roots and damp patches are common. A pair of waterproof hiking boots with good traction will help you move safely through the soft forest floor.
Plan for Mosquitoes in Summer
Late spring through early fall can bring mosquitoes. Use insect repellent and wear long sleeves during those times for comfort.
Visit Early or Late in the Day
To catch the gentle morning or afternoon light and avoid crowds and bugs, plan your hike early or late in the day.
The Lost Forty: Hiking Through Minnesota’s Rare Old-Growth Forest
Tucked inside Minnesota's Chippewa National Forest lies the Lost Forty—a stretch of old-growth forest fiercely untouched by early 20th-century logging. This 144-acre enclave is rare, a grove where towering white pines reach skyward with a quiet authority, and centuries-old hardwoods define a landscape as alive today as it was hundreds of years ago. Hiking here is not just a walk; it’s an encounter with a wilderness that dares you to respect its age and resilience.
The trail through the Lost Forty covers about 2 miles of mostly flat terrain, making it accessible yet rewarding. The soil beneath your boots feels soft and springy, cushioned by layers of pine needles and fallen leaves. As you trek, the trees stand like ancient guards—white pines sprawl with broad branches, red and white oaks flex their muscle, and maples shimmer with muted greens and fiery autumn flames.
Expect no grand summits or sweeping views here; the adventure is in the stillness and detail. Listen for the whisper of wind weaving through needles, the creak of bark responding to the seasons, and the chirp of a thrush challenging the peaceful hush. Mosses and lichens claim fallen logs, inviting you to slow down and notice the forest’s smaller inhabitants.
Though the elevation gain is minimal—roughly 100 feet—carry plenty of water and wear sturdy boots to navigate occasional uneven roots and damp spots. Early morning or late afternoon visits reward hikers with soft, directional light that animates the forest’s textured layers. Avoid mid-summer midday as mosquitoes can test your patience.
Seasonal timing matters here. Spring brings a riot of wildflowers and new growth wrestling upward, while fall lets you move through carpets of colorful leaves, the forest’s way of letting go. Winter’s quiet blanket shifts the landscape, casting a hushed dignity over the pines and oaks, though trail conditions demand careful preparation.
Planning your excursion means respecting the Lost Forty’s character: it’s a forest that offers no shortcuts to spectacle but rewards those ready to walk through time. Pack light but prepared, keep your pace steady, and let the forest’s calm strength shape your journey. Here, adventure is not conquering but witnessing something fiercely itself, a reminder that some places persist beyond human reach—waiting for the careful and curious to pass through.
