88 Acre Marquette County WI Hunting Property…

Neshkoro, WI
Marquette
If you’ve been searching for a property that hunts right and feels like camp the second you drive down the owned road leading to this 88± acres in Crystal Lake Township Marquette County, just outside of Neskoro. The backbone of this land is the oaks—strong, high ground ridge that produce the kind of acorn crop that keeps deer on your property and set up along the oak edges in the fall, and you’re right in the action as whitetails feed and stage before slipping into cover. Cover is where this property signs. The tamarack low ground creates a thick, secluded sanctuary—exactly where mature bucks want to spend daylight hours. It’s tough, quiet, and naturally protective. And right along that transition line where the oaks meet the tamarack, you’ve got a textbook edge habitat. That’s your stand location. The food plots only make it better. They’re positioned to pull deer out of the bedding areas and give you predictable movement patterns—early season, rut, and late season. Add in the established trail system, and you can slip in and out of stand locations. And then there’s the camp possibilities. Picture a simple setup tucked into the pines—a place to hang your gear, fire up the grill, and tell stories after dark. Whether camp is a tent, camper or cabin you build opening day feels bigger. This is where traditions get built—kids’ first deer, opening weekend rituals, and the kind of memories that stick. Key Features: Prime oak ridges with strong mast production Tamarack sanctuary creating ideal bedding & security cover Established food plots, trail system & enclosed blind Contact Land Pros Marty Griepentrog 608-617-9924 [email protected] or Travis Hamele 608-697-3349 [email protected]
